Abstract: In an arrangement for a seat (2) in a vehicle, the seat is movable in a longitudinal direction along a plane (33) which slopes relative to the horizontal plane. The subframe of the seat (2) consists of devices (30, 31) fastened respectively to the vehicle and to the seat, which devices consist of two substantially similar triangular supporting frames. Resetting between a predetermined driving position and a likewise predetermined resting position is made possible by a control device (16) which is fastened to the device (30) which is itself fastened to the vehicle, which control device cooperates with a locking device fastened to the seat so that during a relocating movement between forward and rear positions of the seat the locking device (17) becomes free from at least one locking position between the vehicle seat and the device (30) fastened to the vehicle.

Abstract: A gear lever (7) is arranged between the driving seat and the passenger seat in a truck. The gear lever (7) incorporates a disengageable locking mechanism (34) by means of which it is possible to lower the gear lever (7) from a substantially vertical position of use to a position in which it does not limit the driver's mobility in the cab. When the gear lever (7) has been lowered, the driver can move from the driving side to the passenger side of the truck.
