Abstract:
1. A deceleration responsive vehicle seat for an occupant of a vehicle, comprising: a seat having a frame structure adapted to support the occupant and to absorb the weight of the occupant and other forces exerted by said occupant on the seat, said frame structure including a seat cushion frame assembly, said seat cushion frame assembly comprising a seat cushion frame and a seat cushion being supported by said seat cushion frame, the seat cushion frame assembly supporting a first intermediate seat belt guide member, said frame structure further including a backrest frame assembly, said backrest frame assembly comprising a backrest frame, a backrest cushion being supported by said backrest frame, the backrest frame assembly supporting a second intermediate seat belt guide member, said seat allowing to support said occupant in an upright sitting normal position, said seat further including frame structure fixation means adapted and arranged to fix said frame structure to the vehicle, wherein the frame structure fixation means provide mobile attachment of the seat cushion frame assembly and the backrest frame assembly to the vehicle, and wherein the seat cushion frame assembly and backrest frame assembly are linked to another in a mobile manner, said seat further including a seat belt system with a seat belt for said occupant, which seat belt system includes: a seat belt having a lap part and a shoulder part, said shoulder part embodied to extend across the front of the occupant, a seat belt retractor engaging on said seat belt shoulder part, a seat belt shoulder guide member mounted on said backrest frame assembly, wherein said seat belt shoulder part passes along said seat belt shoulder guide member to said retractor, wherein the shoulder belt part passes from the retractor along the first and second intermediate seat belt guide members to the shoulder guide member, and wherein said mobile linking of the cushion frame assembly and backrest frame assembly allows for change in mutual spatial orientation of the first and second intermediate seat belt guide members that are respectively supported by the cushion frame assembly and backrest frame assembly upon pre-collision braking or collision induced deceleration with respect to their mutual spatial orientation in a normal driving position of the seat, and wherein said first and second intermediate seat belt guide members are arranged such that said change in mutual spatial orientation upon pre-collision braking or collision induced deceleration causes a lengthening of the path of the seat belt shoulder part between the retractor and the shoulder guide member.
