Abstract

The present invention provides a seat which reduces the load applied to a first fastening part, is unlikely to cause wrinkles or slack in a surface cover, and also makes surface sheet attachment and detachment simple. To this end, a first fastening part (30) and a second fastening part (40) of a seat (1) are attachable and detachable; hence, it is possible to easily exchange a surface cover (4) according to the season and to clean the surface cover (4). The second fastening part (40) attachably/detachably connects the surface cover (4) and the rear-surface cover (5) to one another. As a result, the second fastening part (40) appropriately reduces the load directly applied to the first fastening part (30), making it possible to prevent damage to the first fastening part (30), and making it unlikely for wrinkles or slack to occur in the surface cover (4). Furthermore, symbols expressing the surface sheet (4) attachment/detachment order are provided on the first fastening part (30) and the second fastening part (40).

Description

Sheet

The present invention relates to a sheet in which a front cover is detachable from a back cover.

Conventionally, Japanese Utility Model Publication No. 4-39747 is known as a technology in such a field. The seat described in this publication includes a foam cushion material molded into a seat shape, a bag-like covering material that covers the cushion material and is fixed to the cushion material side, and covers the front side of the covering material.

However, since the periphery of the front cover is only detachable with the slide fastener with respect to the periphery of the rear cover, when the rear cover is attached to the front cover in a tension state, a load is applied to the slide fastener. There are problems that the slide fastener is damaged and that the surface cover is likely to be wrinkled or loosened.
Also, since the periphery of the front cover is only detachable from the periphery of the back cover with a slide fastener, when attaching the front cover to the back cover, the assembly order of the slide fasteners is difficult to understand, and the assembly order is incorrect. There is also a problem that it cannot be assembled correctly.

An object of the present invention is to provide a sheet that reduces the load applied to the first fastening portion, is less likely to be wrinkled or loosened on the surface cover, and can be easily assembled on the surface cover.

The present invention provides a seat formed by connecting a front cover and a back cover of a seat part via a detachable first fastening part,
The hanging portion formed by suspending a part of the surface cover on the cushion material side is provided with a second fastening portion that detachably connects the cushion material and the surface cover,
The first fastening portion and the second fastening portion are provided with a symbol indicating an attachment order for attaching the front cover to the rear cover or a removal order for removing the front cover from the rear cover.

In this sheet, since the first fastening portion and the second fastening portion are detachable, the surface cover can be easily replaced or cleaned depending on the season. Further, the front cover and the rear cover are connected by a detachable second fastening portion. As a result, the load directly applied to the first fastening portion is appropriately reduced by the second fastening portion, so that the first fastening portion is prevented from being damaged, and the surface cover is less likely to be wrinkled or loosened. Since the fastening part and the second fastening part are provided with a symbol indicating an attaching order for attaching the front cover to the back cover or a removing order for removing the front cover from the back cover, the front cover is attached by the sign. It can be removed from or attached to the back cover, and the front cover can be easily attached to and detached from the back cover.

The detachable first fastening part is provided so as to extend along the periphery of the back cover and the first fastening half part provided so as to extend along the periphery of the front cover. And a second fastening half that is detachably connected to the first fastening half.

Also, it is preferable that the first fastening portion is a hook-and-loop hook or hook means that can be hooked.

The detachable second fastening portion is provided on the front cover and a third fastening half fixed to the cushion material in a recess extending along the hanging portion on the cushion material side. And a fourth fastening half that is stored in the recess and detachably connected to the third fastening half.
When such a configuration is adopted, the second fastening portion is stored in the recess, and therefore it is possible to appropriately prevent the second fastening portion from hitting the occupant's buttocks and back in the suspended portion.

The symbols are numbers and letters, and are composed of reflective stickers, phosphorescent prints, and uneven three-dimensional display. Therefore, the numbers and letters can be easily identified even in a dimly lit car, and the top sheet can be easily attached and detached.

According to the present invention, the load applied to the first fastening portion is reduced, the surface cover is not easily wrinkled or loosened, and the surface sheet can be easily attached and detached.

It is a perspective view showing a 1st embodiment of a sheet concerning the present invention. FIG. 2 is a cross-sectional view taken along the line II-II in FIG. It is a disassembled perspective view of a sheet | seat. It is a principal part expansion perspective view of a 2nd fastening part.
