The invention relates to a vehicle seat comprising a seat portion and a backrest connected to the seat portion by a hinge mechanism. A seat element selected from among the backrest and the seat portion comprises a shell, which is made of a plastic material and the side edges of which are overmolded onto composite reinforcement inserts. Each of the inserts comprises a core perpendicular to the medium plane of the seat element, and two side flanges parallel to the medium plane of the seat element. The insert is formed by assembling two composite parts having an L-shaped cross-section and forming a portion of the core and one of the side flanges of the insert.

Vehicle seat and method for making same

A vehicle seat includes a seat back having a support frame coupled to a seat foundation. The seat back also further includes a deformable seat shell adapted to assume various shapes between initial position and final positions in response to variable rearward loads applied by a seated passenger. The seat shell is coupled to the support frame by a compliant shell-motion controller via upper and lower motion-control links. The motion-control links allow pivotal motion, and at least one of the links includes a spheroidal joint. A link foundation extends between and interconnects the upper and lower motion-control links and is coupled to the support frame so that the link foundation does not move during seat shell deformation. The shell-motion controller may be pre-assembled as part of a backrest or the motion-control links may be formed after the link foundation is attached to the support frame.

Controllable comfort shell for vehicle seat

A vehicle seat includes a backrest coupled to an upwardly extending support frame. The backrest includes a deformable seat shell adapted to assume various shapes between an initial position and a final position in response to variable rearward loads applied by the torso of a seated passenger. The seat shell is coupled to the support frame by a compliant shell-motion controller via upper and lower motion-control links. At least one of the motion-control links includes a flexural portion configured to bend about a pivot axis to establish a flexural joint. The lower motion-control link may include a flexural joint and/or a revolute joint, and the upper motion control link may include a flexural, revolute, or spheroidal joint.

Vehicle seat backrest with flexural joint motion-control

A seat back includes a backrest formed of a first polymeric material for supporting an occupant. A bracket formed of a different material than the first polymeric material of the backrest is anchored to the backrest for coupling to a seat cushion. A reinforcing composite layer is connected to the backrest and is formed of a second polymeric material and a plurality of fibers impregnated in the second polymeric material. The first polymeric material of the backrest is mechanically engaged with the bracket free of melt bonding between the first polymeric material of the backrest and the bracket. The first polymeric material of the backrest is melt bonded to the second polymeric material of the reinforcing composite layer integrating the backrest, the bracket, and the reinforcing composite layer.
