ABSTRACT:
A safety vehicle seat structure comprising a seat having a backrest and a seat portion. A support frame is secured to the seat and comprises a pair of spaced-apart vertical back support members each pivotally secured at their upper ends to a respective side of the backrest. Each vertical back support member has a lower end secured to a respective one of two horizontal supports located below the seat portion. At least one connecting member is secured to the seat portion forwardly of the back support members and extends therebelow to pivotally interconnect with a displaceable lever framework whereby actuation of the lever framework will cause displacement of the seat between two positions relative to the support frame. A belt attachment clamp is secured to the horizontal support members and adapted to receive and rigidly engage a portion of a retaining belt extending therethrough. A safety strap structure is also provided for immovably securing the seat and support frame to a rigid external structure and further provides shock absorbing means for damping the forward movement of a person's body when subjected to a shock.
