33. 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, said frame structure further including a backrest frame assembly, said backrest frame assembly comprising a backrest frame and a backrest cushion being supported by said backrest frame, 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 body, wherein the frame structure fixation means provide mobile attachment of the seat cushion frame assembly and the backrest frame assembly to the vehicle body, preferably pivotal attachment, 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, wherein the frame structure is such that—
upon pre-collision braking and/or collision induced deceleration—
inertial forces result in the seat cushion frame assembly performing a motion so as to move the seat cushion forward and simultaneously the backrest cushion tilting forward, the seat cushion frame assembly preferably also causing a relative inclination of the seat cushion frame so as to cause a forward portion of the seat cushion frame to be raised relative to a rear portion thereof. - View Dependent Claims (34)

35. 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, said frame structure further including a backrest frame assembly, said backrest frame assembly comprising a backrest frame and a backrest cushion being supported by said backrest frame, 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 body, wherein the frame structure fixation means provide mobile attachment of the seat cushion frame assembly and the backrest frame assembly to the vehicle body, preferably pivotal attachment, 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 further includes at least; a seat belt end terminal, preferably a retractor, mounted on said frame structure or a seat belt end terminal, preferably a retractor, to be mounted on the vehicle body, a seat belt shoulder guide member mounted on said backrest frame assembly, additional seat belt members, e.g. an anchoring member and a seat belt lock member, mounted on said frame structure on opposite sides of the seat cushion, wherein said seat belt system furthermore includes one or more intermediate seat belt guide members provided in said frame structure at one or more locations spaced from each other and from the shoulder guide member and the end terminal, each of said intermediate seat belt guide members being adapted to guide said seat belt thereby defining a path for said seat belt between said end terminal and said seat belt shoulder guide member, and wherein the frame structure is such that upon pre-collision braking and/or collision induced deceleration the spatial orientation of said end terminal, one or more intermediate seat belt guides and said shoulder seat belt guide changes with respect to said spatial orientation in normal position thereby causing a lengthening of the path of the seat belt between the end terminal and the shoulder guide member, preferably of at least 10 centimetres, more preferably between 10 and 50 centimetres, most preferable between 10 and 30 centimetres.

39. A vehicle seat having a backrest frame and a three-point seat belt system, wherein the shoulder guide for the seat belt is part of the backrest frame and is placed at an angle with respect to the horizontal, the backrest frame further including an inner seat belt guide adjacent to the shoulder guide, which inner seat belt guide also is a part of the backrest frame and is also placed at an inclined orientation, the angle between the inner seat belt guide and the adjacent shoulder guide being less than 90 degrees, the seat belt arriving at the inner seat belt guide from below, then passing from the front to the back of said inner seat belt guide over the guide and then towards the back of the shoulder guide from where the seat belt passes over the shoulder guide to the front of the backrest frame so that it may the then pass over the torso of the occupant, preferably the effective width of the shoulder guide being at least twice the width of the seat belt.
