ABSTRACT:
The automobile vehicle seat features a seat back hinged on the seat pan and device for blocking the seat back with respect to the seat pan in the event of forward impact. The automobile vehicle seat features a height adjustment mechanism. The device for blocking the seat back includes a cam pivot-mounted on the shaft, and a weight joined to the cam, with the cam arranged so upon impact the cam, pivots by the inertia of the weight and the cam engages with a lower edge of the seat back frame, such that pivoting of the seat back is prevented by bracing of the cam against the lower edge and such that this produces a high radial force on the height adjustment shaft, thereby limiting the possibilities of rotation of the height adjustment shaft.
