Breve descripción de la invenciónBrief Description of the Invention

La presente invención es un dispositivo para regular de manera automática la altura de una barra de soporte de apoyo mediante un sistema de regulación formado por unos elementos que fijan el conjunto telescópico. El conjunto formado por el sistema de elementos rozantes permite la extensión del soporte cuando se acciona el pulsador de manera automática, bloqueando la posible reducción de longitud del conjunto cuando éste experimenta un esfuerzo vertical hacia arriba cuando no se acciona el pulsador.The present invention is a device for automatically adjust the height of a support bar support through a regulation system consisting of elements that fix the telescopic assembly. The set formed by the system of friction elements allows the extension of the support when the button is operated automatically, blocking the possible set length reduction when it experiences a vertical effort up when the button.

Para recoger el conjunto se dispone de un accionamiento frontal que desbloquea el sistema mediante una barra corredera que acciona un elemento giratorio para soltar la barra superior del sistema de freno, permitiendo el movimiento libre de la parte extensible del mecanismo.To collect the set you have a front drive that unlocks the system using a bar slide that drives a rotating element to release the bar upper brake system, allowing free movement of the Extensible part of the mechanism.

La regulación automática en extensión de este soporte del sistema de retención infantil permite una mejor adaptación al piso del suelo del vehículo, aumentando el confort en la instalación del sistema y la seguridad del conjunto del dispositivo en caso de accidente, ya que se asegura el correcto posicionamiento de la barra de soporte que evita la rotación del conjunto.Automatic extension regulation of this Child restraint system support allows better adaptation to the floor of the vehicle floor, increasing comfort in the installation of the system and the security of the whole device in case of accident, since it ensures the correct positioning of the support bar that prevents the rotation of the set.

Descripción detallada de la invenciónDetailed description of the invention

El dispositivo objeto de la presente invención es un sistema de regulación automática de altura de una barra de soporte de un sistema de retención infantil para el transporte de niños en un vehículo automóvil, que permite mejorar el confort y la seguridad del ocupante de este sistema de retención infantil.The device object of the present invention it is an automatic height adjustment system of a bar support of a child restraint system for the transport of children in a motor vehicle, which improves comfort and occupant safety of this child restraint system.

Estructuralmente, tal y como se ha comentado anteriormente y puede observarse en las Fig. 1 y 2, el sistema consta de dos tramos de soporte, un tramo superior (1) y un tramo inferior (2). El tramo superior está fijado a la carcasa del sistema de retención infantil y contiene el sistema de elementos rozantes que actúa sobre el tramo inferior. Este sistema de elementos rozantes es un conjunto de piezas que fijan el tramo inferior (2) de la barra de soporte cuando se ejerce algún tipo de fuerza vertical con tendencia a disminuir la longitud total del soporte para evitar el movimiento de rotación a través del eje de las anillas Isofix que tendría en caso de brusca deceleración longitudinal del vehículo.Structurally, as mentioned above and can be seen in Figs. 1 and 2, the system It consists of two support sections, an upper section (1) and a section lower (2). The upper section is fixed to the system housing child restraint and contains the system of friction elements which acts on the lower section. This system of elements friction is a set of parts that fix the lower section (2) of the support bar when some kind of vertical force is exerted with a tendency to decrease the total length of the support to avoid the rotation movement through the axis of the Isofix rings that would have in case of sudden longitudinal deceleration of the vehicle.

Este sistema de fijación de posición permite una regulación continua de la longitud de la barra de soporte, dado que puede quedar fijado a cualquier altura, siempre que se encuentre entre el rango mínimo y máximo posible, consiguiendo una adaptación óptima y asegurando el contacto entre la base de la parte inferior del soporte (2) y el piso del vehículo.This position fixing system allows a continuous adjustment of the length of the support bar, since it can be fixed at any height, provided it is between the minimum and maximum possible range, achieving an adaptation optimal and ensuring contact between the bottom of the bottom of the support (2) and the floor of the vehicle.

El sistema de elementos rozantes que fija la posición del tramo inferior (2) respecto al tramo superior (1) está compuesto por dos piezas en forma de U, una superior (3) y una inferior (4), unidas mediante una rueda dentada (5). Estas dos piezas (3) y (4) son las que consiguen bloquear el desplazamiento relativo entre el tramo superior (1) y el tramo inferior (2) del support leg mediante el aumento de la fuerza de rozamiento resultante de su actuación. La rueda dentada (5) permite distribuir uniformemente el esfuerzo entre ambas piezas, además de conseguir que mediante un único accionamiento a modo de pulsador (6) se libere totalmente el tramo inferior dado que ambas piezas (3) y (4) en forma de U se separan del tramo inferior (2) de la barra de soporte.The system of friction elements that sets the position of the lower section (2) with respect to the upper section (1) is composed of two U-shaped pieces, one upper (3) and one bottom (4), joined by a cogwheel (5). These two pieces (3) and (4) are the ones that block the movement relative between the upper section (1) and the lower section (2) of the support leg by increasing the friction force resulting from his performance. The cogwheel (5) allows distribution evenly the effort between both pieces, in addition to getting that by means of a single push-button drive (6) be released totally the lower section since both pieces (3) and (4) in U-shape are separated from the bottom section (2) of the bar support.

El sistema para desbloquear la posición de ambos soportes está compuesto por el propio pulsador (6), una carcasa exterior (7) donde se ubican unos flejes (8) de contacto que empujan el pulsador (6) hacia el exterior impidiendo que pueda desbloquearse el sistema a no ser que el usuario pulse el accionamiento.The system to unlock the position of both supports is composed of the push button (6), a housing exterior (7) where contact strips (8) are located that push the button (6) facing outwards preventing it from being unlocked the system unless the user presses the drive.
