1. An automotive seat comprising:
- a foam main pad which is so foamed in a mold that a central portion of its upper surface is recessed;
a sub pad bonded to said main pad such that said sub pad conforms in shape to said upper surface of said main pad, wherein said sub pad is also bonded to a covering member; and
a decorative recessed groove provided between said main pad and said sub pad such that it is defined laterally of said main and sub pads;
wherein said sub pad is formed into an uneven shape, so that the size of said sub pad is conformed to that of said main pad, the free end part of said covering member being inserted into a boundary between said sub pad and said main pad.

Abstract
An automotive seat comprising a main pad having an unevenly shaped upper surface, a sub pad bonded to such upper surface of the main pad and a covering member bonded to the sub pad, and a method of forming the automotive seat.
According to the method disclosed, a sub pad of a flat-plate-like slab material and a covering member are firstly pressed and bonded together in a shape conforming to the unevenly shaped upper surface of a main pad, and then those two bonded elements are bonded to the upper surface of the main pad.
In this way the seat is obtained in which the sub pad is bonded positively along the unevenly shaped upper surface of the main pad.

3. A method of forming an automotive seat, comprising the steps of:
-
providing a pre-formed main pad which has a recessed area defined in its central portion; applying subsequently pressure by means of a press working device to a foam sub pad and a covering member to reshape said foam sub pad into an uneven shape, and at the same time bonding said sub pad and covering member together, such that a non-bonded surface of said sub pad conforms in shape to said upper surface of said main pad while an upper surface of said covering member is formed in conformity with an outer contour of said seat; and thereafter, bonding said sub pad with said covering member bonded thereto to said upper surface of said main pad by means of an adhesive. - View Dependent Claims (4, 5, 6, 7)

8. An automotive seat comprising:
-
a foam main pad having an upper surface which is recessed in a central portion thereof and raised at side portions thereof; a sub pad/covering member subassembly extending across the entire upper surface of said foam main pad and being laminated thereto, said subassembly comprising a covering member and a generally planar sub pad reshaped to conform in shape to said upper surface of said main pad, said covering member being laminated to said reshaped sub pad along an upper surface thereof during reshaping thereof; and a decorative recessed groove provided along a boundary between said main pad and said sub pad such that it is defined laterally of said main pad and said sub pad, a portion of said covering member being inserted into said recessed groove.
