Abstract

Seat material having a covering member integrally provided on a foamed material and a patterned portion of the covering member formed by recessing the covering member in a stripe pattern and a method for producing such seat material comprising the steps of preparing a foaming mould having a patterning protrusion for recessing the covering member in a stripe pattern and clamping the covering member onto the patterning protrusion by a clipping member which is buried by the foamed material.

Claims

1. A method of producing seat material having a covering member integrally attached to foamed material comprising the steps of:

preparing a foaming mould including lower and upper mould halves, and at least said lower mould half being of the type having at least one patterning protrusion thereon;

placing a covering member into said lower mould half on an inner face thereof;

securing said covering member to said at least one patterning protrusion of said lower mould half by clipping at least one clipping member onto said covering member and said patterning protrusion for securing said covering member to said patterning protrusion;

pouring resin material to be foamed into said foaming mould for filling said covering member for producing said seat material having said covering member integrally attached to foamed material and having said at least one clipping member therein; and

curing said resin material for producing said foamed material.

2. A method of producing seat material having a covering member integrally attached to foamed material as set forth in claim 1, wherein said clipping in said securing step includes the providing of at least one clipping member of the type having teeth on finger portions thereof for positively securing said covering member to said at least one patterning protrusion of said lower mould half.

3. Seat material having a covering member integrally attached to foamed material and produced by the method of claim 1.

4. Seat material as in claim 3, wherein said covering member includes an outer front skin layer and an inner wadding layer.

5. A method of producing seat material having a covering member integrally attached to foamed material comprising the steps of:

preparing a foaming mould including lower and upper mould halves, and at least said lower mould half being of the type having at least one patterning protrusion thereon;

placing a covering member into said lower mould half on an inner face thereof;

securing said covering member to said at least one patterning protrusion of said lower mould half by clipping at least one clipping member of the type having at least one tooth on finger portions thereof onto said covering member and said patterning protrusion for securing said covering member to said patterning protrusion;

pouring resin material to be foamed into said foaming mould for filling said covering member for producing said seat material having said covering member integrally attached to foamed material and having said at least one clipping member therein; and

curing said resin material for producing said foamed material.

6. Seat material having a covering member integrally attached to foamed material and produced by the method of claim 5.
