摘要:
A seat comprising a cover member (3) bonded to a molded polyurethane foam (2) along a surface of the latter, wherein, instead of a continuous one-piece cover member, a cover member cut and split into individual parts or a locally-cut cover member is used, and portions of the cover member parts to be bonded or necessary portions of the locally-cut cover members are buried and fixed in grooves of the molded polyurethane foam (2) to construct a three-dimensional seat shape.

A decorative member such as a welt or a button attached to a surface layer of a seat cushion, and a method and apparatus for forming such a decorative member are disclosed. In the method and apparatus, an upper plate is disposed for vertical movement relative to a lower plate, and a pair of holding members defining an insertion space between their upper end portions are vertically or horizontally movably mounted on the lower plate. A covering and a core providing the decorative member are inserted in the insertion space, and a seat cushion is placed between the upper and lower plates with its surface layer facing the holding members. The upper plate is urged downward toward the lower plate to compress the seat cushion onto the holding members while, at the same time, enclosing the core in the covering in the cooperation with the holding members. High frequency current is supplied to complete the decorative member and to weld it to the surface layer of the seat cushion.

A locking device for a slide rail in a vehicle seat, and particularly for a pair of slide rails which each have an upper rail and a lower rail, said upper rail being formed by two half rail members. The locking device in the present invention includes a pair of stoppers which are slidably provided within the two half rail members respectively of the two upper rails such as to be vertically movable therein, a plurality of holes formed in the lower rails, into which holes the stopper is to be engaged, and a lever rod which is operatively connected with the stopper. Single operation of the lever rod causes engagement and disengagement of the stoppers into and from the holes for locking and unlocking of the slide rails at one time.

In a method of manufacturing a permeable seat cushion, a permeable fabric material is pressed between a pair of dies while being heated and wetted with steam to render the fabric temporarily unpermeable to provide a seat covering of bag-like structure. A first precut filler pad is bonded to the seat covering, and a second precut filler pad is then bonded to the first filler pad. A frame is mounted together with springs and other necessary elements on the thus obtained assembly, and the seat covering is anchored at its pheripheral edges to the frame to complete the seat cushion.
摘要:
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.
摘要:
An apparatus for manufacturing an automotive seat, comprising a revolvable body, plural padding securing members or plural upper molding dies provided around the revolvable body, and a horizontally movable plural lower molding dies disposed under the revolvable body, the lower molding dies being movable horizontally relative to said revolvable body.Disclosed also is a method for manufacturing an automotive seat, using such apparatus.According to those apparatus and method, the manufacturing steps are carried out smoothly, with one step being effected during another step, and by virtue of the lower molding dies being horizontally moved, the apparatus can be installed in a small place.
摘要:
A seat member providing a support structure of a seat in a vehicle is integrally formed of a synthetic resin material and includes a seat base portion and wing or flap portions. The seat base portion is formed with a plurality of openings and is partly thinner than the remainder to provide desired resiliency. The flap portions are formed with a plurality of openings or corrugations and are also partly thinner than the remainder to provide additional resiliency. Portions functioning as suspension springs may be integrally formed with the seat base portion together with a frame including upper rails of a slide rail unit. Reinforcing wires may be embedded in both the seat base portion and the flap portions.
