Description

[Detailed explanation of the idea] The present invention relates to an improvement of a vehicle seat.

Vehicle seats with a bag-shaped backrest cover placed over the backrest frame are often seen in front seats of automobiles, etc., but in conventional vehicle seats of this type, there is a seat on the lower edge of the side of the backrest cover. Not only does it sag, causing an unsightly appearance, but the safety belt locking portion is located in the gap formed between the lower edge of the side of the backrest cover and the backrest frame when the backrest is returned to its normal state after tilting forward. There are many inconveniences such as the insertion of

Therefore, attempts have been made to attach rubber strings to the lower edge of the sides of the backrest cover and lock the rubber strings to the seat frame to prevent the formation of slack or gaps. However, it is difficult to completely eliminate the above-mentioned disadvantages, and there is a strong demand for the development of a vehicle seat that does not have the above-mentioned disadvantages.

The present invention was completed with the aim of providing a vehicle seat that met the above-mentioned demands, and the illustrated embodiment will be described in detail below.

Reference numeral 1 denotes a bag-shaped cover main body formed by sewing or other means from synthetic resin leather material, cloth, etc. The hem end of the cover main body 1 is formed with an inward folded part 1b, and at least one of the cover main bodies 1 Vertical cuts 1c, 1c are provided in the folded portion 1b located at the lower end of the side portion 1a.

Reference numeral 2 denotes a horizontally elongated shape-retaining core plate made of a rigid thin plate such as a hard synthetic resin plate, which is attached to the inner surface of the lower end of the side portion 1a of the cover main body 1. Cuts 2at2a are provided with narrowed portions 2a/, 2a/ at the ends, and a rubber ring of a flat belt with the abutting portions of both ends sewn into the cuts 2a, 2a is attached at its bisected position. When engaged, a rubber string 3 is stretched between both end portions of the shape-retaining core plate 2, and only the rubber string 3 of the shape-retaining core plate 2 with the rubber string 3 is exposed on the back side of the folded portion 1b. The cover body 1 is housed in the folded part 1b, and the upper edge of the folded part 1b is sewn to the cover main body 1, thereby forming the backrest cover 4 as a whole.

Reference numeral 5 designates a backrest frame, and the backrest frame 5 is pivotally attached to the seat frame 6 with the lower edge portions of its legs 5a, and can be held at a desired inclination angle by an inclination adjustment mechanism (not shown). The backrest cover 4, which is covered by the frame 5, has the rubber string 3 inserted and held in the lower edge portion of the leg portion 5a before the backrest frame 5 is pivoted to the seat frame 6, so that the elasticity of the rubber string 3 is maintained. Cover main part 1
The lower edge of the side portion 1a is brought into close contact with the leg portion 5a.

With this structure, the backrest cover 4 covered by the backrest frame 5 has a shape-retaining core plate 2 attached to the inner surface of the lower end of the side portion 1a of the bag-shaped cover main body 1, and also has a shape-retaining core plate 2. Shape core plate 2
Since the rubber string 3 stretched between both ends of the backrest frame 5 is locked to the lower end blade of the leg portion 5a of the backrest frame 5, the lower edge of the side portion 1a is under the elastic force of the rubber string 3. Since it is always in close contact with the leg portion 5a through the shape-retaining core plate 2, the lower edge of the side portion 1a does not sag, giving it a good appearance and providing decorative effects such as properly concealing the interior. Furthermore, since no gap is formed between the lower end edge of the side portion 1a of the backrest cover 4 and the leg portion 5a of the backrest frame 5, when the backrest is returned to its normal state after being tilted forward. This has the advantage of being able to accurately prevent the safety belt locking part installed next to the seat from being accidentally inserted into the gap, making it impossible to use the safety belt or causing damage to the backrest cover. .

Therefore, the present invention completely eliminates the inconveniences found in conventional vehicle seats of this type, and has the advantage of being simple in structure and easy to work with, so it can be provided at low cost, and has extremely practical value. It is a big thing.
