Description

  The present invention relates to a seat cushion side finisher mounting structure in which a synthetic resin side finisher that covers a reclining device or the like is mounted on a side frame of a vehicle seat cushion.

  An elevating mechanism for elevating and lowering the seat cushion is laid on the seat cushion of the vehicle, and this elevating mechanism is placed on a slide mechanism that moves the elevating mechanism in the front-rear direction. Therefore, the elevating mechanism and the slide mechanism can appropriately adjust the predetermined height and position of the seat cushion in accordance with the body shape and driving posture of the driver who is seated.

  Further, a side finisher that covers a part of the seat cushion and the vicinity of the side portion of the side frame to which the seat cushion is attached is attached to the side portion of the seat cushion. This side finisher is provided with various mounting holes and recesses, and operation knobs for operating the reclining mechanism, slide mechanism, lifter mechanism, etc. provided on the side frame side through these mounting holes and recesses are provided on this side finisher. Located on the side of the finisher.

  Therefore, this side finisher covers the reclining mechanism, the sliding mechanism, and the side of the lifter mechanism together with the side portions of the seat cushion and the side frame as described above, and prevents these mechanisms from being exposed to the outside. And the aesthetics of the whole sheet are kept.

  By the way, such a side finisher may be deformed or damaged instantaneously due to the tension of the seat belt, for example, when a collision accident occurs while the vehicle is running. Further, the side finisher may be damaged by applying an artificial external force load such as inadvertently kicking with a foot when getting on and off.

On the other hand, in order to avoid breakage and damage of the side finisher, for example, Patent Document 1 discloses a side finisher in which a thin steel plate is overlapped and reinforced at least at a portion where the seat belt contacts.
Further, for example, Patent Document 2 discloses a structure in which a plurality of reinforcing ribs that protrude toward the seat cushion side are provided on the inner surface side of the side finisher in the vertical direction so as to reinforce the side finisher.

In addition, when the side finisher is provided with reinforcing ribs as described in Patent Document 2, the cost of the side finisher itself is increased, and “sink” generally generated in a synthetic resin molded product having ribs deteriorates the appearance. There was an inconvenience.

  The present invention has been made by paying attention to the conventional problems as described above, and without any processing on the side finisher side, that is, processing for reinforcing the side finisher on the side frame on the seat cushion side. An object of the present invention is to provide a seat cushion side finisher mounting structure that can realize reinforcement of the side finisher easily and at low cost.

To achieve the above object, the seat cushion side finisher mounting structure according to the present invention is a seat cushion in which a synthetic resin side finisher that covers a reclining device or the like is attached to a side frame that supports a vehicle seat cushion. Side finisher mounting structure,
The side frame is provided with a stay that contacts the inner surface of the side finisher , and the stay is a wire fixed to the side frame .

With this configuration, the side finisher itself made of synthetic resin is not reinforced with an iron plate or reinforcing ribs are provided on the side finisher itself, so the manufacturing process of the side finisher is not increased, cost increases can be avoided, and resin molding This eliminates the problem of “sink”. And, with the stay attached to the side frame side of the seat cushion, the desired reinforcing effect of the side finisher can be obtained at a low cost by an extremely simple assembly process and configuration.
Further, since the stay is made of a wire, the stay itself can be obtained at a low cost, and the side frame of the stay can be fixed and attached at a time by welding or the like when processing the side frame.

According to the side finisher mounting structure for a seat cushion of the present invention, the following effects can be obtained.
(1) By performing the process for reinforcing the side finisher on the side frame on the seat cushion side, the side finisher can be reinforced easily and at low cost.
(2) Since the side frame is provided with a wire as a stay that contacts the inner surface side of the side finisher, the side finisher is reinforced when the side finisher is reinforced from the inner surface side and an impact is applied from the outside. Breakage and damage can be prevented without deformation.

(3) Since the stay that contacts the inner surface of the side finisher provided on the side frame is made of wire, the stay itself can be obtained at a low cost, and it can be fixed to the side frame and welded when processing the side frame. This can be done at once.

Hereinafter, a seat cushion side finisher mounting structure according to an embodiment of the present invention will be described in detail with reference to the drawings.
