Es otro objeto de la invención un dispositivo de seguridad antiatrapamiento que no precisa desactivación alguna ya que sólo es activo cuando se mueve la luna ó el techo corredizo.Another object of the invention is an anti-trapping safety device that does not require any deactivation since it is only active when the moon or the sliding roof is moved.

Es otro objeto de la invención un dispositivo de seguridad antiatrapamieπto que está facultado para pro- porcionar una reacción inmediata.Another object of the invention is an anti-trapping safety device that is empowered to provide an immediate reaction.

Para el logro de estos objetivos, el dispositivo de la invención reivindica un perfil de goma ó similar dotado de al menos un conducto hueco en su interior y un elemento sensor susceptible de detectar la variación de presión producida dentro de tal conducto.To achieve these objectives, the device of the invention claims a rubber or similar profile provided with at least one hollow duct inside and a sensor element capable of detecting the variation in pressure produced within said duct.

Cuando una presión externa sea aplicada sobre perfil elástico, el conducto actúa como transmisor de la variación de la presión externa aplicada de forma que el sensor se presión situado en un extremo del mismo detecta esa variación de presión y genera una señal eléctrica correspondiente .When an external pressure is applied on an elastic profile, the conduit acts as a transmitter of the variation of the external pressure applied so that the pressure sensor located at one end thereof detects that pressure variation and generates a corresponding electrical signal.

Esta señal eléctrica es procesada por una unidad electrónica de control, de forma que produce una parada y retroceso de la ventana o techo corredizo, evitando de esa forma daños ocasionados por atrapamiento entre el perfil elástico y el elemento de cierre, puerta ó cris- ta."*This electrical signal is processed by an electronic control unit, so that it causes a stop and recoil of the sliding window or roof, thereby avoiding damage caused by entrapment between the elastic profile and the closing element, door or glass. .

En la hoja de planos que se acompaña, se aprecian con detalle todos los particulares de la invención, así como algunos otros ampliatorios, y en ella y sin carác- ter limitativo alguno, se representa como sigue: - La Figura li, representa una puerta de un vehículo que incorpora un perfil elástico resaltado de la invención .In the accompanying plan sheet, all particulars of the invention, as well as some other extensions, can be seen in detail, and in it and without any limiting character, it is represented as follows: - Figure li, represents a door of a vehicle incorporating a highlighted elastic profile of the invention.

- La Figura 2§, muestra una sección transversal de un perfil suoerior elástico de luna, donde se observa el volumen hueco de la goma.- Figure 2 § shows a cross-section of an upper elastic profile of the moon, where the hollow volume of the rubber is observed.

- La Figura 3* , representa un conjunto de elevalu- ñas, con motor-reductor y unidad de control aplicable con la invención .- Figure 3 * represents a set of lifts, with motor-reducer and control unit applicable with the invention.

- La Figura 4§, muestra el detalle de un sensor de presión utilizable con la invención.- Figure 4 § shows the detail of a pressure sensor usable with the invention.

- La Figura 5i, muestra la unidad electrónica de control y sus conexiones.- Figure 5i shows the electronic control unit and its connections.

De acuerdo con la fig. 1-, apreciamos una puerta (1) de un vehículo, con la ventanilla (15) y el perfil elástico superior (4) de la invención en la zona superior que supone la porción en la que existe la posibilidad de atrapamiento. Este perfil transmitirá la presión, variación de presión, que se aplique desde el exterior en la dirección de la flecha ( ), en dirección a la salida tubular (3) del conducto interior de la goma, así como el conector (2).According to fig. 1-, we appreciate a door (1) of a vehicle, with the window (15) and the upper elastic profile (4) of the invention in the upper area that represents the portion in which there is the possibility of entrapment. This profile will transmit the pressure, pressure variation, that is applied from the outside in the direction of the arrow (), in the direction of the tubular outlet (3) of the inner duct of the rubber, as well as the connector (2).

Según la fig. 2¿, observamos un perfil elástico (4) :ue puede ser de ésta u otra forma diferente, en el cual apreciamos el conducto interno (8) el cual finaliza en el sector tubular (3) (fig. 1*2). Este conducto (8) es el encargado de transmitir la presión originada en su interior como consecuencia de la presión exterior (M) generada por un atrapamiento, y recorre toda la longitud del perfil (4), estando generalmente cerrado por uno de sus extremos y abierto por el otro. La presión exterior (M) vendrá originada por la subida del cristal (9) de la ventanilla (9) el cual al encon- trarse un obstáculo entre su borde superior y el perfil (4) determinará la citada presión.According to fig. 2 ¿, we observe an elastic profile (4): which can be of this or another different form, in which we appreciate the internal duct (8) which ends in the tubular sector (3) (fig. 1 * 2). This conduit (8) is responsible for transmitting the pressure originated inside as a result of the external pressure (M) generated by a trap, and runs the entire length of the profile (4), being generally closed at one end and open at the other. The external pressure (M) will be caused by the rise of the glass (9) of the window (9) which, when an obstacle is found between its upper edge and the profile (4) will determine said pressure.

De la fig. 32, destacamos la llegada del sector tubular (3) de la fig. la a la unidad electrónica (10), incluyendo esta unidad, entre otros un elemento sensor capaz de generar una señal de alarma que será procesada, provocando inmediatamente la parada e inversión del sentido de giro del motor-reductor (13) a través de los terminales (12). La parada del motor-reductor (13) se transmite a través del sistema elevaluπas (14), traduciéndose en una parada del cristal (9) de la ventanilla (15) y posterior e inmediata bajada de la misma.From fig. 32, we highlight the arrival of the tubular sector (3) of fig. the to the electronic unit (10), including this unit, among others a sensor element capable of generating an alarm signal that will be processed, immediately causing the stop and reversal of the direction of rotation of the motor-reducer (13) through the terminals (12). The motor-reducer stop (13) is transmitted through the elevator system (14), resulting in a stop of the window (9) of the window (15) and subsequent and immediate lowering thereof.

Particularmente, de la fig. 4i, destacamos en deta- He el sensor de presión (6) y la forma de conexión del sector tubular (3) y conector (2) al dicho sensor a través de una entrada (7), apreciándose aquí también las terminales (5) de salida del sensor.Particularly, of fig. 4i, we highlight in detail the pressure sensor (6) and the way of connecting the tubular sector (3) and connector (2) to said sensor through an inlet (7), the terminals (5) also being appreciated here sensor output

Según la fig. 5 , se describe la unidad electrónica de control con la entrada de aire (7) del sensor de presión (6) que facilita la conexión del conector (2) desde el exterior a la unidad electrónica de control (10). En el lado opuesto, puede también apreciarse la forma de conexi n de la unidad (10) al motor-reductor (13) por medio de dos terminales de inserción (12) que facilitan el montaje de la repetida unidad al dicho motor-reduc¬ tor .According to fig. 5, the electronic control unit with the air inlet (7) of the pressure sensor (6) which facilitates the connection of the connector (2) from the outside to the electronic control unit (10) is described. On the opposite side, the form of connection of the unit (10) to the motor-reducer (13) can also be appreciated by means of two insertion terminals (12) that facilitate the assembly of the repeated unit to said motor-reduction ¬ tor.

El motor-reductor puede ser de cualquier tipo, según se hacía notar, y en la fig. 53 se ha representado el conjunto de conexión directa al mismo, destacándose aquí y a los efectos oportunos que el sistema es también aplicable, de igual forma, a unidades electró- nicas externas al motor, utilizando en ese caso cableado aéreo para las conexiones al mismo.The motor reducer can be of any type, as noted, and in fig. 53, the direct connection assembly has been represented, highlighting here and to the appropriate effects that the system is also applicable, in the same way, to electronic units external to the motor, using in this case aerial wiring for the connections thereto.

El interior del conducto (8) puede incorporar cualquier tipo de fluido que sea susceptible de variar su presión al aplicar desde el exterior una fuerza.The inside of the duct (8) can incorporate any type of fluid that is capable of varying its pressure by applying a force from the outside.

El sensor de presión puede ser de tipo galga exten- siométrica o de cualquier otro, de modo que es activado en el momento en que detecta una variación de presión, proporcionando la señal eléctrica de alarma correspondiente .The pressure sensor can be of the strain gauge type or of any other, so that it is activated at the moment it detects a variation in pressure, providing the corresponding electrical alarm signal.

La protección antiatrapamiento será activa durante la subida del cristal de la ventanilla y será efecti- va al aplicar una presión externa sobre cualquier punto del perfil elástico por cualquier persona situada en el interior del vehículo, produciéndose una parada y consiguiente retroceso del cristal. The anti-trapping protection will be active during the rise of the window glass and will be effective by applying external pressure on any point of the elastic profile by any person located inside the vehicle, resulting in a stop and consequent recoil of the glass.
