Description

The The present invention relates to a passenger seat assembly for a vehicle with a passenger seat and one at least Partially dashboard-free front passenger side, a passenger seat for a previously described passenger seat assembly and a vehicle with a passenger seat arrangement according to the invention.

It are different vehicle seats with adjustment options known in a quiet location.

DE 198 28 255 A1 describes a vehicle seat with a rest position. To protect against slipping the seat cushion is moved in the direction of travel in a forward, predetermined position and inclined backwards in the rest position. Furthermore, an additional belt is provided.

DE 201 03 450 U1 describes a vehicle seat which is pivotable downwardly in a rest position obliquely backwards.

EP 1 116 653 B1 describes an adjustable passenger seat of an aircraft. The passenger seat can be adjusted into a lounger with an extended legrest.

DE 199 04 100 A1 describes an airbag assembly with a space in front of the passenger seat that is panelless. The airbag is arranged in a centrally located console below the windshield or on an A-pillar for the passenger or additionally for drivers, each with an oblique direction of movement.

It Object of the invention, a passenger seat assembly, a passenger seat and to provide a vehicle of the type mentioned, the vehicle comfort and variable usage options with an enlarged Passenger space increase under consideration of passive safety requirements.

The Task is based on a passenger seat arrangement according to the The preamble of claim 1 and a passenger seat in conjunction solved with its characterizing features. The following dependent claims give advantageous developments the invention again.

According to the invention the task solved by a restraint device is arranged with an airbag in the dashboard-free space, wherein the airbag is essentially straightforward in the dashboard-free space unfolded in the vehicle longitudinal direction in front of the passenger seat and arranged in front of the front passenger seat in the vehicle longitudinal direction is. Because the airbag can deploy in the direction of travel, is the passive safety of passengers on the passenger side increases, as this is the main direction of movement of a vehicle is and thus is a preferred absorption direction to emerging, to reduce impact energy in a collision and catch. The airbag with at least one chamber or with a Main chamber in several chambers is in the vehicle longitudinal direction inflated. Thus, a direct and short retention path opposite to the main forward movement of the vehicle realized. A complicated inflating process diagonally or transversely to the vehicle longitudinal direction, as the above-described state of Technique is avoided.

According to a preferred embodiment, the retaining device is arranged on a front body support, in particular a windshield cross member and / or a bulkhead. The arrangement of the restraint device in the form of an airbag module on a front body support has several advantages. The elimination of the dashboard on the passenger side minimizes the weight of the vehicle, reducing fuel consumption and CO ₂ emissions as a result. In addition, there is a flexible versatile usable passenger interior, without having to do without a conventional restraint device. When attaching a restraint device to a body cross member, the components reduce due to the omission of the dashboard on the passenger side and shrink.

According to one important inventive idea of the invention is the at least one Passenger seat on a sliding device with a in direction Windscreen mounted far forward displaceable displacement, which is preferred at least up to an overlap area in imaginary extension of a driver's dashboard extends. The at least one passenger seat can be thus move very far forward in the passenger compartment, so that an ample space is created in front of the passenger seat. Another advantage over a conventional one Passenger seat is that the backrest is significantly better in a horizontal position to the rear by means of pivoting devices pivot and lock in each of these positions.

According to an embodiment further developing the invention, a support device for lower extremities, such as legs and feet, in the lower footwell on the passenger side. The support device may be arranged on the passenger interior limiting side surfaces and be pivotable or hinged in a lock. The passenger seat can thus be transformed into a comfortable couch with a substantially horizontal rest position, the medical It is advantageous for those seeking relaxation.

Around the passenger seat with a rest position even during the Train the vehicle in a safe transport situation is on the support device as a Fußstemmbrett trained footrest arranged. A vehicle occupant in the passenger seat in a horizontal rest position can thus no further than the obliquely or vertically upward Fußstemmbrett with appropriate braking maneuvers slip forward.

According to one preferred embodiment, the bulkhead as a Fußstemmbrett provided surface and has the Advantage that for the Fußstemmbrett not more Components are required and the bulkhead a multiple function due.

According to one Another important inventive idea is the omission of the passenger side Dashboard such a large space ready, taking into account a very far pushed forward displacement that two Seats can be arranged on the passenger side, whereas on the driver's side, only one seat is arranged. Behind the Seats are usually a rear seat, which extends over the driver and passenger side.

The Task is further by a passenger seat for a Passenger seat assembly with features described above characterized solved that the passenger seat a support device for a particularly complete intake of lower extremities such as legs and feet having. The support device is thus located completely on the passenger seat and is not on the passenger seat and Distributed on the passenger interior limiting side surfaces.

According to one preferred embodiment is the support device mehrgelenkig, in particular formed in three parts. By doing so leaves the support device at the passenger seat in the usually arranged seating position compact zoom out and for a desired rest position swing.

According to the invention the front-passenger seat has a movement mechanism for tilt adjustment, by means of a backrest of the passenger seat in a almost horizontal rest position is pivotable. This has the advantage that from a conventional passenger seat a comfortable Lying and resting position can be created, which is a special good regeneration of the passenger permits. In conventional Passenger seats can be the backrest often only pivot at an obtuse angle with an inclined plane and thus creates a non-optimal and medically not advantageous Regeneration.

According to one Another important idea of the invention is the support device a mechanical device for inclination reinforcement in a essentially horizontal position swiveling. The lower extremities can thus in a favorable horizontal position brought the passenger seat to a medically healthy Make a lounger.

advantageously, is a front portion of a seat surface of the passenger seat stored higher than another area. The lower extremities are thus stored higher than the rest of the thorax. This is a very relaxing regenerative rest for one Passenger. In addition, offers such a arranged seat a certain braking effect when a horizontal rest position during a vehicle ride is taken. An above-mentioned Fußstemmbrett additionally promotes a possibly possible Forward of the co-driver.

Around a passenger in any position according to legal Strapping to keep straps is at least one upper Gurtpunkt a three-point belt on the backrest of a passenger seat arranged. The three-point belt thus moves in every position of the backrest from an upright sitting position to a horizontal rest position With.

at A preferred embodiment is the three-point belt arranged on the passenger seat. This has the advantage that the Passenger seat flexible forward and backward on a sliding device can be postponed without other accompanying facilities to provide the three-point belt.

For better support in different positions of the Passenger seat is the passenger seat, preferably with a H belt system educated. Such H-belt systems are mainly from the vehicle racing known and can in the inventive Passenger seat be advantageous.

In order to a person in a horizontal resting and lying position one better position-stable hold, especially during extreme acceleration processes has, preferably a headrest on the passenger seat can be locked formed pivotable at an angle of at least 90 °. Thus, the person resting on the passenger seat can not go back slip.

According to a further important idea of the invention, the front passenger seat is rotatably mounted about a substantially horizontal axis. This has the advantage that the entry and exit easier becomes.

Furthermore is a vehicle with a passenger seat assembly according to above provided features described. A vehicle with a described Passenger order is extremely comfortable as it is has a usable passenger interior, which also variable is. The front passenger seat has a significantly improved lying surface on the passenger side and thus creates better regeneration possibilities for the passenger sitting on the passenger side.

According to one Another preferred embodiment provides a vehicle with a passenger order according to the above Feature at least one other place, the asymmetric seat distribution in the vehicle. For this purpose, preferably Vehicle a fastening device for at least two successively arranged, in particular displaceable, seats a, preferably displaceable, rear seat on the passenger side on, whereas on the driver's side with a dashboard Seat behind a, preferably movable, rear seat in the Essentially arranged over the same vehicle length is. Due to the enlarged passenger interior, due to the omission of the dashboard on the passenger side leaves thus another seat with another person in the vehicle take.

According to one other important inventive concept can advantageously the Passenger door designed to extend forward in the direction of travel because there is no dashboard on the passenger side is available. The exit options or loading and Unloading on the passenger side are thus comfortably improved and facilitated.

It It is understood that the above and below to be explained features not only in the specified Combination, but also usable in other combinations.

The The invention will become more apparent hereinafter with reference to the drawings explained. Show it:

1 a cross-sectional view of a passenger seat assembly according to the invention with a very large displacement,

2 a passenger seat according to the invention in a passenger arrangement according to the invention,

3 a passenger seat according to the invention according to 2 with a first extended part of a multi-part support device,

4 the passenger seat according to 2 and 3 with a fully extended support device and

5 the passenger seat according to the invention according to the 2 to 4 in a horizontal rest position.

The 1 shows in cross-section schematically a passenger seat arrangement according to the invention 1 with a passenger seat 2 and a dashboard-free front passenger side. In front of the passenger seat 2 is a restraint device 3 arranged. The restraint device 3 includes an airbag module 4 with an airbag 5 , The restraint device 3 is on a front body cross member, in the 1 shown case on a windshield cross member 6 arranged. The windscreen cross member 6 is formed in this particular embodiment with two trays, which are offset from each other. The airbag module 4 is in an inner tub 7 attached. In detail, such a structure is described in separate descriptions of inventions with the internal file numbers 200770610, 200770617 and 200770618.

The at least one passenger seat 2 is on a displacement device 8th with one towards the windscreen 9 stored far forward displaceable displacement. The displacement is extended due to the elimination of a passenger-side dashboard by at least 300 to 600 mm, depending on the vehicle type, forward. For better clarity is dashed line a driver's dashboard 10 located. The displacement of the passenger seat 2 preferably extends at least up to an imaginary overlap or approach area 11 in extension of the driver's side dashboard 10 , Such a passenger seat arrangement according to the invention 1 has the advantage that an extremely flexible passenger interior can be realized with a high degree of variability and thus with a high degree of vehicle comfort with different passenger seat arrangements. In addition, the vehicle weight is reduced due to the elimination of the passenger-side dashboard. The usual passive safety today is the arrangement of the restraint device 3 right in front of the passenger seat 2 guaranteed.

According to the invention, two seats can be arranged one behind the other on the passenger side in front of a rear seat due to the extremely large displacement, whereas on the driver side only a driver's seat is arranged in front of a rear seat. Thus, the number of seats is increased. It can be transported more people with the vehicle, which he the economy of the vehicle increased. Thus, three rows of seats can thus be arranged one behind the other on the passenger side, whereas two rows of seats are provided on the driver side.

In accordance with another important inventive concept, the passenger seat assembly includes 1 a support facility 12 on the lower extremities, such as legs and feet, of the vehicle occupant, not only partially but advantageously completely, can be stored in the passenger seat. The support facility 12 can be arranged hinged or swivel in the lower footwell on the passenger side. The support facility 12 is attached to a footwell of the passenger interior limiting side surface and is swung out as needed, as shown schematically in the 1 is shown.

According to a further preferred embodiment, as in 2 is shown at the front passenger seat 2 the support facility 12 trained for lower extremities such as legs and feet. The support facility 12 includes in the in the 2 illustrated special embodiment, three parts 13 . 14 . 15 which are connected by means of three joints. The support facility 12 is under the passenger seat by means of the joints 2 swiveling and stowable. 2 shows the passenger seat 2 in a forward shifted position I which is possible due to the windshield 9 extended adjustment of the passenger seat 2 , The dashed line is a seating position II shown. The seating position II corresponds to the usual seating position with a passenger-side dashboard. According to the invention, the passenger seat 2 around a substantially horizontal axis 23 rotatably mounted. The entry and exit is thus facilitated. Due to the larger passenger compartment, a rotation is easier to carry out. A further relief results from the fact that the front passenger door can be formed enlarged in the area of the non-existing dashboard and foot area.

The 3 shows the passenger seat according to the invention from the 2 with the difference that a first part 13 the support facility 12 is swung out and supports the thigh of a passenger. Accordingly, a second part 14 and a third part 15 the support facility 12 under the passenger seat 2 withdrawn. 3 also shows the seating position II with a passenger seat shifted far to the rear 2 on a displacement device 8th ,

The 4 shows the passenger seat according to the invention 2 in a front seating position I and in dashed line a rear seating position II , The 4 is different from the 3 in that the support facility 12 with the three parts 13 . 14 and 15 to lay down the lower extremities, as in the 4 shown completely swung out. The second and third part 14 . 15 the support facility 12 is swung obliquely downwards at an angle, and the first part 13 the support facility 12 is in extension of a seat 16 the passenger seat 2 tilted upward sloping, looking at the extremities from the driver's body down to the feet. A backrest 17 is in the sitting position I arranged upright. In the dashed position II however, the backrest is 17 swung slightly backwards. An unillustrated three-point belt is advantageously at least with the upper Gurtpunkt on the backrest 17 attached. In the preferred embodiment, the three-point belt is fully disposed on the passenger seat.

In order to avoid a Nachvornerutschen the passenger during braking maneuvers, can be on the third part of a Fußstemmbrett 18 be arranged. The footrest board 18 the support facility 12 has the advantage of having the footrest board 18 with the passenger seat 2 in different positions along the displacement path or in the sitting position II with shifts. In a simple embodiment, in which the additional component of a Fußstemmbretts 18 can be omitted forms an intended surface of a below the windshield cross member 6 arranged bulkhead 19 the footrest board 18 ,

The 5 shows the passenger seat according to the invention 2 in a comfortable reclining position similar to a conventional lounger. Such a couch is very advantageous from a medical point of view and creates a particularly good regeneration, which is not possible in conventional configurations of a passenger seat. The backrest 17 is pivoted to a nearly horizontal position to the rear. Also the first part 13 the support facility 12 is in a horizontal position as well as the second and third part 13 and 14 pivoted. Only the seat 16 has an upper front elevated point and a lower rear point. In an alternative embodiment of the passenger seat according to the invention may also be the seat 16 in a horizontal position around a pivot point 20 be pivoted and locked by means of a corresponding pivoting mechanism. By eliminating the dashboard on the passenger side, the lower extremities, such as legs and feet, can be placed far above in the passenger compartment in a newly created leg room. An inventive vehicle with the passenger seat assembly according to the invention 1 can therefore be used more versatile, since the passenger seat 2 can also be used as a comfortable lounger. According to the invention, the passenger door 22 in direction of travel to the front be widened widened, which is shown with dashed lines, and thus increase the boarding and Aussteigekomfort of a vehicle. The widening of a passenger door can also bring optical benefits that give the vehicle, for example, a dynamic and sporty design. The rotatable front passenger seat 2 increases the getting in and getting out of the vehicle.

A headrest of the passenger seat 2 can be locked in a lockable position by at least 90 °, in order to give a vehicle occupant resting in a horizontal position a secure position-stable hold even during extreme acceleration processes and thus to avoid a subsequent slipping.

Especially is based on the drawings for the invention referred to as essential. The figures do not show merely schematic true-to-scale illustrations.
