Abstract: An improved motor vehicle is provided for minimizing personal injuries resulting from collisions. The vehicle has a floor with a recessed area therein and a passenger seat mounted on the floor above the recessed area thereof. The seat includes a seat portion and a back portion. Front and rear braces are pivotally connected at their respective opposite ends to the seat and to the vehicle body or frame. Upon impact, the momentum of the occupied seat pivots the seat from an upright driving position above the recessed area to a reclined impact position within the recessed area such that the impact forces are absorbed by the seat portion of the seat.
