Description

[Detailed Description of the Invention] The present invention relates to the structure of a bottom plate for holding a cushion material used in motorcycle seats, automobile seats, etc.

Generally, when cushioning materials such as pads are used in motorcycle seats, etc., a bottom plate is attached to maintain the shape of the cushion body. Many of these products use mechanical parts when seated, such as the fuel tank of a motorcycle, the door panel or seat frame of a car, or the wooden or metal frame of a furniture seat. There were inconveniences such as damaging other mechanical parts, damaging the seat skin, and generating abnormal noise. Particularly in recent years, as shown in Fig. 1, seats for motorcycles have come to be often used with the tip of the seat body A' extending to the top surface of the fuel tank B. If the rope bottom plate 1' is extended to the upper surface of the fuel tank B, the bottom plate 1' and the surface of the fuel tank B will come into direct contact during riding, causing the above-mentioned problems and causing the upper bottom plate attached to the vehicle body to cannot be extended to a position where it touches the tank surface. However, if the cushion body is made of only cushion material, it is possible to shape the cushion body, but there is a drawback that it is extremely difficult to maintain the shape of the cushion body when riding.

The purpose of this invention is to provide an improved seat bottom plate that does not have the above-mentioned drawbacks.The purpose of this invention is to provide a bottom plate for seats that is improved so that the above-mentioned drawbacks do not occur. The parts are connected and arranged.

The details of the present invention will be described below with reference to the drawings, using an example in which the present invention is applied to a motorcycle seat.

The seat body A shown in the second figure has a bottom plate 1 attached to hold a cushion material 4 constituting a seating portion, and is entirely covered with a skin 5 made of leather or the like.

The bottom plate 1 consists of a hard plate part 1a made of a steel plate or the like, and a soft plate part 1b made of an elastic material that can be bent repeatedly, such as a rubber material or an EVA sheet material.The soft plate part 1b is a hard plate part. As shown in FIG. 3, a rivet 2 and a washer 3 are used to join and connect from the tip of 1a. The soft plate portion 1b is arranged in a predetermined position and length so as to come into contact with the surface of the fuel tank B when the seat body A is attached to the vehicle body. The thickness of the soft plate portion varies depending on the characteristics of the material used or the degree of added load of the seat to which it is applied, but a certain degree of wall thickness is required for a motorcycle seat that is subjected to a large vibration load as in this example. be.

In addition, the hard plate portion 1a and the soft plate portion 1b
The most suitable method for joining and connecting is riveting as in this embodiment, but the method is not particularly limited to this.

In the case of the seat A to which the bottom plate 1 configured in this way is applied, since the elastic soft plate is arranged in the part that directly contacts the fuel tank B, even if the tank surface and the seat surface come into contact, Since the contact force is relaxed, there is no damage to the surface or skin 5 of the fuel tank B, or abnormal noise due to contact, and the soft plate part 1b has a restoring force that can be bent repeatedly, so the cushion It is possible to prevent the material from losing its shape.

Although this example is applied to a motorcycle seat, it can also be applied to an automobile door lining or seat frame, a wooden furniture seat,
Even when the bottom plate of these sheets comes into direct contact with the metal frame, etc., the soft plate part 1
This can be applied by simply changing the shape and location of b.
