Abstract
Abstract An apparatus for forming a vehicle seat, in which two different upper dies are provided above a base table and two different lower dies are movably provided on the base table. At the central part of the base table, there are a pressing means and a rotary means which cause the pressing of one of the two upper dies against one of the two lower dies. Using this apparatus, two different covering members and cushion members are bonded together in good sequence without need for replacement of the dies so as to produce a number of different seats or seat elements.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
348 words
An apparatus for forming a vehicle seat, comprising: a base table in which a first working area, a second working area and a bonding operation area are defined; a pair of first and second lower dies which are moveably mounted on said base table, such that said first lower die is normally located at said first working area, whereas said second lower die is normally located at said second working area, wherein upon said first lower die, a first covering member is to be placed and upon said second lower die, a second covering member is to be placed; a transfer means for transferring said first and second lower dies from their respective first and second working areas towards said bonding operation area on said base table, and for transferring said first and second lower dies from said bonding operation area towards their respective first and second working areas; a pair of first and second upper dies which are provided at said bonding operation area such that they are rotatable and vertically movable with respect to said base table, wherein said first upper die is adapted for securing thereon a first cushion member cushion member; a rotary means for causing rotation of said pair of first and second upper dies in order that one of said two upper dies is to be faced towards one of said first and second lower dies, when the latter is transferred to said bonding operation area; and a pressing means for pressing one of said pair of first and second upper dies against said pair of first and second lower dies; whereby, said first and second covering members are placed on said first and second lower dies, respectively, while said first and second cushion members are secured on said first and second upper dies, respectively, and then, after an adhesive is applied to said first and second cushion members, one of said first and second cushion members is pressed against and bonded to one of said first and second covering members by operation of said transfer means, rotary means and pressing means.
Claim 2
Independent Claim
