On comprendra mieux l'invention à l'aide de la description qui suit faite en référence aux figures annexées suivantes
- figure 1 : croquis d'une batterie pour véhicule thermique à connexions dans le support inférieur, et équipé d'un dispositif de sécurité conforme à l'invention,
- figure 2 croquis de la batterie de la figure 1 en position ouverte,
- figure 3 : croquis montrant la position prise par la batterie en cas de choc.The invention will be better understood with the aid of the description which follows, made with reference to the following appended figures.
- Figure 1: sketch of a battery for a thermal vehicle with connections in the lower support, and equipped with a safety device according to the invention,
- Figure 2 sketch of the battery of Figure 1 in the open position,
- Figure 3: sketch showing the position taken by the battery in the event of an impact.

La batterie représentée à titre d'exemple sur les figures est du type de celle décrite dans le brevet français délivré FR 2.662.121. The battery shown by way of example in the figures is of the type described in the French patent issued FR 2,662,121.

Elle se compose d'un bac (1) dont le socle (2) comporte des bornes femelles (3), et d'un support (4) comportant des bornes mâles (5) et deux sorties (6). Le support (4) sera lui-meme fixé à un support rigide non représenté.It consists of a tank (1) whose base (2) includes female terminals (3), and a support (4) comprising male terminals (5) and two outlets (6). The support (4) will itself be fixed to a rigid support, not shown.

De façon préférentielle, le dispositif de sécurité se compose d'une sangle (7) et d'une plaque (11). Preferably, the safety device consists of a strap (7) and a plate (11).

La sangle élastique (7) est fixée par un anneau (8) au centre d'une des faces latérales du support (4), par exemple une face ne comportant pas de bornes. Ladite sangle se termine par une tige (9), un anneau, un cliquet ou autre moyen d'accrochage, destiné à maintenir par accrochage la sangle élastique (7) sur la plaque (11).  The elastic strap (7) is fixed by a ring (8) to the center of one of the lateral faces of the support (4), for example a face having no terminals. Said strap ends with a rod (9), a ring, a pawl or other hooking means, intended to hold the elastic strap (7) on the plate (11) by hooking.

La plaque (11) est fixée au centre de l'autre des faces (13) qui ne comporte pas de bornes. Elle comporte un pli (12) central parallèle au support et se termine par un crochet (10) ou autre organe d'accrochage, pour recevoir la tige (9). La longueur de la sangle élastique est calculée en fonction de la taille du bac (1). The plate (11) is fixed to the center of the other of the faces (13) which has no terminals. It has a central fold (12) parallel to the support and ends with a hook (10) or other attachment member, to receive the rod (9). The length of the elastic strap is calculated according to the size of the tank (1).

En position normale d'utilisation de la figure 1 la pointe du pli (12) appuie sur un flanc du bac (1). In the normal position of use in FIG. 1, the tip of the fold (12) presses against a side of the container (1).

En cas de choc frontal, la batterie bascule vers l'avant comme sur la figure 3, et le pli (12) de la plaque pénètre dans l'espace libre entre le fond du bac (1) et le support (12) empêchant ledit bac de retomber sur son support après le choc. In the event of a frontal impact, the battery tilts forward as in Figure 3, and the fold (12) of the plate enters the free space between the bottom of the tank (1) and the support (12) preventing said bin to fall back on its support after the impact.

La batterie a donc été déconnectée par le choc et ne peut se reconnecter seule, elle est maintenue hors circuit. The battery was therefore disconnected by the shock and cannot reconnect on its own, it is kept off.

Un simple dégagement de la plaque permet la remise en circuit de la batterie. A simple release of the plate allows the battery to be switched on again.

Le dispositif de sécurité selon l'invention s'applique d'une manière générale à toute batterie montée sur support, du type avec connexions électriques entre batterie et support. The safety device according to the invention applies generally to any battery mounted on a support, of the type with electrical connections between battery and support.

I1 peut être utilisé sur véhicules à moteur thermique, moteur électrique, bateaux, véhicules à deux roues...  I1 can be used on vehicles with thermal engine, electric motor, boats, two-wheeled vehicles ...
