Abstract

Abstract A method of producing a skin-covered pad for a seat, which includes by steps (a) preparing a lower mold which has a cavity formed therein, the mold having projections on a bottom of the cavity; (b) putting a bag-shaped outer skin member into the cavity, the skin member being thermally plastic; (c) putting an upper mold on the lower mold to close the cavity, the upper mold having an aperture formed therethrough; (d) projecting a press member into the cavity through the aperture, the press member having at its work head recesses which are shaped to match with the projections of the lower mold; (e) pressing the recessed work head of the press member against the projections of the lower mold with an interposal of a part of the outer skin member therebetween; (f) heating the work head of the press member thereby to soften the part of the outer skin member; (g) separating the work head of the press member away from the projections of the lower mold; and (h) pouring a liquid material for foamed plastic into the cavity and curing the same.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 184 words
A method of producing a skin-covered pad for a seat, comprising by steps: (a) preparing a lower mold which has a cavity formed therein, said mold having projections on a bottom of said cavity; (b) putting a bag-shaped outer skin member into said cavity, said skin member being thermally plastic; (c) putting an upper mold on said lower mold to close said cavity, said upper mold having an aperture formed therethrough; (d) projecting a press member into said cavity through said aperture, said press member having at its work head recesses which are shaped to match with said projections of the lower mold; (e) pressing the recessed work head of the press member against said projections of the lower mold with an interposal of a part of the outer skin member therebetween; (f) heating said work head of the press member thereby to soften said part of the outer skin member; (g) separating said work head of the press member away from said projections of the lower mold; and (h) pouring a liquid material for foamed plastic into said cavity and curing the same.
Claim 2
Independent Claim 184 words
A method of producing a skin-covered pad for a seat, comprising by steps: (a) preparing a lower mold which has a cavity formed therein, said mold having projections on a bottom of said cavity; (b) putting a bag-shaped outer skin member into said cavity, said skin member being thermally plastic; (c) putting an upper mold on said lower mold to close said cavity, said upper mold having an aperture formed therethrough; (d) projecting a press member into said cavity through said aperture, said press member having at its work head recesses which are shaped to match with said projections of the lower mold; (e) pressing the recessed work head of the press member against said projections of the lower mold with an interposal of a part of the outer skin member therebetween; (f) heating said work head of the press member thereby to soften said part of the outer skin member; (g) separating said work head of the press member away from said projections of the lower mold; and (h) pouring a liquid material for foamed plastic into said cavity and curing the same.
Claim 3
Dependent Claim 23 words
A method as claimed in claim 1, in which the step (g) is carried out while the step (h) is being carried out.
Claim 4
Dependent Claim 47 words
A method as claimed in claim 2, in which said step (g) includes a step (i) of moving said press member to such a position where a front surface of said work head of the press member is flush with an inner wall of said upper mold.
Claim 5
Dependent Claim 28 words
A method as claimed in claim 3, in which the step (f) is achieved by energizing a heater wire embedded in said work head of the press member.
Claim 6
Dependent Claim 29 words
A method as claimed in claim 4, in which said bag-shaped outer skin member is constructed of a layered material which comprises a wadding lined with a thermoplastic leather.
Claim 7
Dependent Claim 36 words
A method as claimed in claim 4, in which the step (c) is so made that a peripheral edge of the skin member is unmovably held between respective peripheral edges of said lower and upper molds.
