Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a vehicle seat such as an automobile, and more particularly to a seat having a suspension.

[Prior Art] Conventionally, a surface of a seat of an automobile or the like is provided with a feeling of unevenness, or a hanging is formed for the purpose of decoration. As shown in (1), when the cushion material 81 is foam-molded, a suspending locking wire 80 is previously arranged inside the cushion material 81 when foam-molding inside the cushion material 81, and this wire 80 is used. The method is well known. In this case, the locking wire 80 is arranged in the substantially central portion of the cushion material 80, and a groove is formed on the surface of the cushion material where the locking wire 80 is located.
85 is formed in advance, the suspending cord 83 is inserted into the groove 85 together with the skin material 82, and the tip end portion of the suspending cord 83 and the locking wire 80 are joined using a C ring 84 or the like. Form a suspension.

A method is also known in which a cross plate of a back frame or a spring spring is used instead of the locking wire 80.

[Problems to be Solved by the Invention] However, in the method of using the locking wire previously arranged inside the cushion material as described above, it is necessary to insert the locking wire when the cushion is foamed. The above disadvantages are unavoidable, the suspending pattern is partial, there are restrictions on the suspending pattern, and furthermore, it is not possible to secure a sufficient suspending distance, so that a deep suspending cannot be formed. In order to solve such a problem, as described above, there is one that uses a cross plate of the back frame or a spring spring instead of the locking wire. When this technique is used for a bucket type seat with a high bank, the following procedure is performed. That is, first, the upper half of the skin material is covered with the cushion material, and then in this state, the same hanging fixing work as described above, that is, the tip portion of the hanging cord and the cross plate or the spring spring are Join with a C ring, etc.
Cover the lower half of the skin. However, when this method is used for a bucket-shaped sheet material having a relatively small opening and a high bank, there is a drawback that the work of covering the lower half of the above-described sheet material becomes extremely complicated.

The object of the present invention is made in view of the above problems.
It is an object of the present invention to provide a seat which has good performance of the cushioning material, forms a deep hanging, and can be easily covered with a bag-shaped skin material in a bucket type seat. .

[Means for Solving the Problems] In order to achieve the above object, the present invention has the following configuration. That is, in a sheet having a frame, a cushion material having a suspending groove and a suspending hole, and a bag-like skin material covering the cushion material, and suspending the skin material with a suspending member, the skin material is While forming a suspending member locking portion in the frame located on the opening side of the skin material when covering, one end of the suspending member is engaged with the skin material, the other end of the suspending member is It is configured to be locked to the hanging member locking portion via a hanging support member located at a position corresponding to the hanging.

A spring spring arranged on the back surface of the seat may be used as the hanging support member.

[Operation] In the seat having a suspending member according to the present invention, the suspending member is locked to the suspending member locking portion formed on the frame via the suspending support member located at a position corresponding to the suspending operation. Therefore, the suspending member is linearly drawn from the seat surface to the frame side at a right angle up to the suspending portion, so that deep suspending can be performed. Further, since the suspending member locking portion is formed on the opening side of the skin material when covering the skin material, the suspending member is hung before covering the skin material, and the skin material is covered. The pulling member can be pulled to engage with the suspending member locking portion. Therefore, even when the opening of the bag-shaped skin material is small, the work becomes easy.
