Abstract

An arrangement for a battery in a motor vehicle, including: a recess for the battery which is arranged in the vehicle; and a battery to be vertically inserted into the recess in a first mounting direction up to a mounted position. The recess includes at least one fixed blocking surface relative to the recess, which contacts the periphery of the battery in the mounted position for horizontally immobilizing the battery in every direction.

Claims

1-13. -13. (canceled)

14. An arrangement of a battery in a motor vehicle which comprises:

a housing for the battery, which housing is arranged in the vehicle;

a battery configured to be introduced vertically into the housing in a direction of mounting as far as a mounted position;

wherein the housing comprises at least one wedging face which is fixed with respect to the housing which is in contact with the periphery of the battery in the mounted position so as to immobilize the battery horizontally in all directions.

15. The arrangement as claimed in claim 14, wherein the wedging face is formed by an annular interior face forming a rigid surround that horizontally surrounds the battery and that is in contact along its entire length with the periphery of the battery in the mounted position so as to block horizontal movements of the battery in all directions.

16. The arrangement as claimed in claim 15, wherein at least one pad of elastically deformable material is interposed horizontally with preload between the annular interior face and the battery in the mounted position so as to absorb any mounting clearances there are between the battery and the annular interior face so as to ensure that the battery is immobilized relative to a chassis of the vehicle horizontally in all directions.

17. The arrangement as claimed in claim 14, wherein the wedging face is formed of an interior face of a rigid frame which is fixed to the chassis of the motor vehicle.

18. The arrangement as claimed in claim 14, further comprising vertical buffer means against which the battery abuts in its mounted position.

19. The arrangement as claimed in claim 18, wherein the annular wedging face has a frustoconical shape which collaborates with a counterpart that surrounds the battery horizontally so as to block vertical movement of the battery in the direction of mounting when it is in the mounted position.

20. The arrangement as claimed in claim 19, wherein the counterpart is produced as an integral part of the battery.

21. The arrangement as claimed in claim 19, wherein the counterpart is formed of the frustoconical exterior face of a rim which projects horizontally outward from the vertical faces of the battery.

22. The arrangement as claimed in claim 14, further comprising locking means for locking the battery in the mounted position and which block vertical movement of the battery in the opposite direction to the direction of mounting.

23. The arrangement as claimed in claim 22, wherein the locking means comprises at least one hook-shaped catch that is mounted to pivot between a released position in which the battery is free to slide vertically and a locked position in which the battery is trapped in the housing in the mounted position.

24. The arrangement as claimed in claim 23, wherein, in its locked position, the hook-shaped catch is configured to catch under a free lip of the rim.

25. The arrangement as claimed in claim 23, wherein, in its locked position, the hook-shaped catch is configured to catch on a ring borne by the battery.

26. The arrangement as claimed in claim 23, wherein an axis of pivoting of the hook-shaped catch is arranged, in a direction of gravity, in line with a point of contact between the battery and the hook-shaped catch in the locked position.
