Patent Images
1. A supporting part for supporting an occupant in a seat comprising:
- a multilayered member having a supporting layer for supporting said supporting part on the seat;
an intermediate layer of thermally reversibly deformable material supported by said supporting layer and deformable from a predetermined first shape to a second shape conforming to the contours of the occupant in the seat;
a heating layer sandwiched and affixed between said supporting layer and said intermediate layer for heating said intermediate layer to a predetermined temperature to form said second shape, said heating layer including strip conductor heating elements embedded in a resin layer which are energized by an external power supply; and
a covering layer affixed to said intermediate layer for enclosing said intermediate layer and said heating layer between said covering layer and said supporting layer.

Abstract
A supporting part for a seat has at least one plastic layer made of a material composed of thermally reversibly deformable material. The plastic layer can be shaped from a first shape into any predeterminable second shape at a shaping temperature higher than its temperature of use and can be fixed in this reversible shape at a temperature range lower than the shaping temperature. This layer can also be returned to its first shape by reheating it up to the shaping temperature. Another layer arranged as a heating layer is provided to apply a thermal treatment to the intermediate layer made of a material that can also o be reversibly deformable.

8. A seat for supporting an occupant in a vehicle comprising:
-
a seat cushion having a resilient foam pad at least partially encased in a cover material;
a seat back having a resilient foam pad at least partially encased in a cover material;
a supporting part affixed between said foam pad and said cover material of at least one of said seat cushion and said seat back, said supporting part comprising a multilayered member having an intermediate layer of thermally reversibly deformable material supported by, said foam pad and positioned adjacent said cover material, said intermediate layer being deformable from a predetermined first shape to a second shape conforming to the contours of the occupant in the seat, and a heating layer sandwiched and affixed between said foam pad and said intermediate layer for heating said intermediate layer to a predetermined temperature to form said second shape, said heating layer including strip conductor heating elements embedded in an resin layer which are energized by an external power supply and a plurality of carbon fibers embedded in said resin layer and electrically connected to said strip conductor heating elements. - View Dependent Claims (9, 10, 11, 12, 13)
