A device for forming headrest in a foaming die, which includes a lid engagement mechanism operable to keep a lid member engaged in an injection nozzle placed in the foaming die, thereby preventing leakage of liquid foaming agent from the injection nozzle. Further, the device includes a lid disengagement mechanism operable to disengage the lid member from the injection nozzle and an injection gun movable vertically. The lid disengagement mechanism includes a pressure element provided at the injection gun. Upon downward movement of the injection gun, the pressure element acts on the lid member, so that the lid member is disengaged from the injection nozzle and the injection gun is then engaged with the injection nozzle, thereby allowing liquid foaming agent to be injected into a trim cover assembly placed in the foaming die.

Device for forming headrest

A seat back assembling device designed for engaging two hook members of an incomplete seat back unit with each other to close the corresponding opened side thereof so as to form a complete seat back. In the device, all required operative mechanisms are collectively disposed to automatically assemble such incomplete seat back unit. Namely, the incomplete seat back unit is pressingly supported by a pressing mechanism, and the two hook members of the incomplete seat back unit are provisionally secured and brought to engagement with each other, by a positioning mechanism and a positioning/engaging mechanism. The hook members thus engaged together are subject to a further positive mutual engagement by way of a positive engagement mechanism. All those mechanisms are disposed as close as possible to a part of the device, such as a support base frame, without requiring other separate robot systems.

Device for assembling a seat back of a seat

A system for covering a cushion member with a sack-like trim cover assembly, which includes a securing mechanism with support element and a covering guide mechanism. The sack-liked trim cover assembly is turned inside out and secured on the securing mechanism, with the cushion member secured thereon in an opposedly faced relation with such turnedover trim cover assembly. Both cushion member and trim cover assembly are located precisely by the support element at a given position on the securing mechanism. The securing mechanism and covering guide mechanism are operated in a direction opposite to each other, thereby displacing the cushion member to an opened side of the trim cover assembly, while the trim cover assembly is being turned over again by the covering guide mechanism. The system further includes a pressing device for pressing a part of the cushion member to make it accesible for securement of an anchor member of the trim cover assembly therewith so that the cushion member is neatly covered with the trim cover assembly. A hog ring fitting mechanism is provided for automating such securement of anchor member to the cushion member, which permits all the operations of the system to be effected automatically.

System for covering a cushion member with a trim cover assembly

A seat with a trim cover assembly having plural stitches thereon, wherein the stitches are arranged in a non-parallel relation with one another on one unitary sheet of the trim cover assembly which is affixed over a cushion body. Those patterns of stitches are formed at one time by means of a multiple-needle sewing machine.

Seat with a trim cover assembly having plural stitches thereon

A method of feeding a unitary sheet of trim cover assembly to a multiple-needle sewing machine for creating plural stitches thereon, in which non-parallel stitches are formed among parallel stitches on the trim cover assembly by means of a guide member having a sloped portion. The sloped configuration of the guide member causes formation of sloped, folded portion in the trim cover assembly, and the trim cover assembly with such folded portion is fed to the multiple-needle sewing machine.
