The device shown in the figures includes a means (1,2) capable of developing a resistance to compression (1) or to stretching (2) and a set of two elements (3) and (4) sliding one by relative to each other and having facing walls (3A, 3B) and (4 A) capable of compressing, walls (3B) and (4A), or of stretching, walls (3A) and (4A), said means ( 1,2), placed between said facing walls, when a tensile force (F) is exerted, by the belt (5), on said two elements (3,4).
La résistance élastique du moyen (1,2) peut être progressive, dégressive ou les deux entre le début et la fin de sa compression ou de son étirement. The elastic resistance of the means (1,2) can be progressive, degressive or both between the start and the end of its compression or of its stretching.
Les éléments (3) et (4) peuvent comporter un moyen permettant leur déverrouillage en cas de choc. The elements (3) and (4) may include a means enabling them to be unlocked in the event of an impact.
Selon diverses réalisations de l'invention, le moyen (1,2) est : - un ressort travaillant à la compression (1) ou à la traction (2) ; According to various embodiments of the invention, the means (1,2) is: - a spring working in compression (1) or in tension (2);
<Desc/Clms Page number 2><Desc / Clms Page number 2>
- un corps travaillant à l'écrasement (1) ou à l'étirement (2) (solide ou fluide). - a body working on crushing (1) or stretching (2) (solid or fluid).
Selon d'autres particularités de l'invention : - les éléments (3) et (4) comportent un moyen (6), du type butée, apte à limiter la course de leur déplacement relatif, ladite butée ayant une position fonction du type de moyen (1,2) utilisé ; - les éléments (3) et (4) comportent des moyens (7) du type ouvertures de passage, aptes à permettre leur fixation en un point quelconque de la ceinture (4) ; - l'un des éléments (3,4) comporte un moyen (8), du type trou, apte à permettre sa fixation, par l'intermédiaire d'une vis ou d'un boulon, en un point quelconque du siège. According to other particularities of the invention: - the elements (3) and (4) comprise a means (6), of the stop type, capable of limiting the stroke of their relative displacement, said stop having a position depending on the type of medium (1,2) used; - The elements (3) and (4) comprise means (7) of the passage opening type, capable of allowing their fixing at any point of the belt (4); - one of the elements (3,4) comprises a means (8), of the hole type, capable of allowing its fixing, by means of a screw or a bolt, at any point of the seat.
Le dispositif selon l'invention peut être associé à un autre dispositif, mécanique ou électronique, apte à modifier la résistance du moyen (1,2) en fonction de la vitesse du véhicule et du poids de l'usager de manière à venir, en cas de choc frontal, toujours en limite maximale de course. The device according to the invention can be associated with another device, mechanical or electronic, capable of modifying the resistance of the means (1,2) as a function of the speed of the vehicle and of the weight of the user so as to come, in frontal impact, always at the maximum stroke limit.
Le dispositif selon l'invention peut être également placé entre le siège et le châssis ou la carrosserie du véhicule pour agir en combinaison avec celui ou ceux placés sur la ceinture de sécurité. Dans ce cas, le siège comporte un moyen permettant son déverrouillage en cas de choc. Toutefois, il doit pouvoir se stabiliser définitivement quelque soit le niveau de déplacement qu'il aura atteint. The device according to the invention can also be placed between the seat and the chassis or body of the vehicle to act in combination with that or those placed on the seat belt. In this case, the seat includes a means allowing it to be unlocked in the event of an impact. However, it must be able to stabilize definitively whatever the level of movement it has reached.
En cas de choc frontal, le processus d'actionnement de l'ensemble est le suivant - tension ceinture puis déverrouillage du siège ; - mise en action des divers dispositifs amortisseurs après leur déverrouillage éventuel. Les éléments (3) et (4) peuvent être du type représenté à la figure 3 et comporter chacun 4 parois orthogonales dont les parois (3A), (3B), (4A) et (4B) qui sont parallèles entre elles, la paroi (4B) étant reliée au reste de l'élément (4) par des bras (9,10) coulissant à l'intérieur d'ouvertures pratiquées sur la paroi (3B). In the event of a frontal impact, the actuation process for the assembly is as follows - belt tension then unlocking of the seat; - activation of the various damping devices after their possible unlocking. Elements (3) and (4) can be of the type shown in FIG. 3 and each comprise 4 orthogonal walls, the walls (3A), (3B), (4A) and (4B) which are parallel to each other, the wall (4B) being connected to the rest of the element (4) by arms (9,10) sliding inside openings made on the wall (3B).
L'élément (4) vient en butée (6) contre la paroi (3B) de l'élément (3). The element (4) abuts (6) against the wall (3B) of the element (3).
Selon d'autres particularités de réalisation de l'invention : - le volant et les pédales comportent un moyen apte à permettre leur déplacement en cas de choc frontal ainsi qu'éventuellement les airbags de passagers ; - le siège, le volant et les pédales comportent un moyen apte à permettre leur déplacement simultané en cas de choc frontal. According to other particular features of the invention: - the steering wheel and the pedals include a means capable of allowing their movement in the event of a frontal impact as well as possibly the passenger airbags; - The seat, the steering wheel and the pedals include a means capable of allowing their simultaneous movement in the event of a frontal impact.
Le poids de l'usager peut être déterminé par préprogrammation ou par des capteurs placés sur le siège. The weight of the user can be determined by preprogramming or by sensors placed on the seat.
Pour que le siège puisse avancer sur une plus grande longueur, il est nécessaire que celui-ci soit le plus reculé possible avant un éventuel accident et ce quelle que soit la taille du passager. De ce fait, il est préférable que ce soit la position du volant et des pédales qui soit réglable et non la position du siège comme cela se fait habituellement. In order for the seat to be able to move for a longer length, it must be as far back as possible before a possible accident, regardless of the size of the passenger. Therefore, it is preferable that it is the position of the steering wheel and pedals that is adjustable and not the position of the seat as is usually done.
<Desc/Clms Page number 3><Desc / Clms Page number 3>
Ce réglage peut être manuel ou préprogrammé. Le siège peut cependant être réglable sur sa hauteur. This setting can be manual or preprogrammed. The seat can however be adjustable over its height.
Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés pour lesquels on pourra prévoir d'autres variantes, en particulier dans : - les formes et les dimensions des éléments (3) et (4) ; - leur position sur la ceinture ou le siège ; - le type de moyen développant la résistance à la compression ou à l'étirement ; sans pour cela sortir du cadre de l'invention. Of course, the invention is not limited to the embodiments described and shown for which other variants can be provided, in particular in: - the shapes and dimensions of the elements (3) and (4); - their position on the belt or the seat; - the type of means developing resistance to compression or stretching; without departing from the scope of the invention.
