Abstract
The invention relates to a vehicle seat, preferably multiple-seater, which is deformable at the centre thereof and makes it possible to respond to deformation stresses in the event of an accident, impact or crash. In the case of a three-seater seat, the seat is primarily formed by four legs (10), a central seat portion (12), two end seat portions (11) and three backrests (13). The seat portions are bordered by two side bars (18) and one front bar and one rear bar. The front and rear bars are each formed by a central bar (14) or (16) which is extremely flexible, while the end bars (15, 17) of the end seats (11) are extremely rigid. The invention can also be used in aircraft seats.
