Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can prevent the internal parts of a reclining mechanism from being exposed, and can improve the appearance quality by reducing the gap between a seat back and a shield. The present invention relates to a vehicle seat that can be used for a long period of time by preventing breakage of an elastic cover member for shielding a gap.

[0002]

2. Description of the Related Art Conventionally, a reclining mechanism is usually incorporated in an automobile seat, and a shield is provided on a side portion of the seat to prevent the internal parts of the reclining mechanism from being exposed and deteriorating the appearance quality. At the same time, the reclining notch guide portion on the upper cover portion of the shield is provided with an elastic cover member for shielding the gap to improve the design and protect the functional components in the seat.

However, recently, there has been a tendency to reduce the gap between the components in order to improve the appearance quality. As a result, when the reclining mechanism is operated to tilt the seat back, the reclining notch guide portion is formed. There is a problem that the formed elastic cover member for shielding the gap has no place to go after deformation, bends in a complicated manner, bites into the parts of the reclining mechanism and becomes dirty, and furthermore, the cover member is damaged by repeated bending. There is a problem that the durability is lost and the durability is lost.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems and can prevent the occurrence of a gap even when the reclining mechanism is operated. The appearance quality can be improved without being exposed, and even when the seat back is tilted back and forth, the elastic cover member for shielding the gap does not cut into the parts of the reclining mechanism and become dirty or damaged. It has been completed for the purpose of providing a vehicle seat that can be used continuously for a long time.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a vehicle seat according to the present invention is provided with a seat back which is adjustable in angle by a reclining mechanism at a rear portion of a seat cushion, and has a reclining portion at a side portion thereof. A shield that covers the mechanism is installed, and an upper cover of this shield is provided with a notch guide section in the front-rear direction in which an elastic cover member for gap shielding is connected to the notch edge, and the upper arm of the reclining mechanism inserted through this is provided. A gap between the seat back and the shield, wherein a recess is provided at a lower portion of the seat back for receiving the jumping-up portion of the elastic cover member which is flipped up by the operation of the upper arm, the seat being guided by the elastic cover member. Is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. The drawings show a case where the present invention is applied to a front seat of an automobile. Reference numeral 1 denotes a seat cushion, 2 denotes a seat back provided at a rear portion of the seat back so as to be able to tilt forward and backward, and the seat back 2 is a seat cushion 1 The angle is adjustable by a reclining mechanism provided at the rear end of the side of the seat cushion, and a shield 3 is mounted on the side of the seat cushion 1 with a clearance between the seat cushion 2 and the seat back 2 as small as possible.
Is covered by the shield 3, and the above points are basically the same as those of the conventional seat structure.

In the present invention, as shown in FIG. 1, a notch guide portion 5 in the front-rear direction for guiding an upper arm 4 of a reclining mechanism is formed in an upper cover portion of the shield 3. The notch edge of the notch guide portion 5 has a flexible elastic cover member 6 for shielding a gap.
On the other hand, the lower part of the seat back 2 is provided with a recess 7 which can receive the flip-up portion of the elastic cover member 6 flipped up by the upper arm 4 during the reclining operation by notching the seat back pad 2a. Is formed.

The shield 3 is composed of an outside shield 3a and an inside shield 3b. An upper arm 4 of a reclining mechanism (in the drawing, also serves as a seat back frame) is provided on the upper cover of the shield 3. The notch guide portion 5 is formed in the front-rear direction for guiding the notch guide portion, and the notch edge portion before and after the notch guide portion 5 is always kept closed so that the gap of the notch guide portion 5 is not visible from the outside. However, when the seat back 2 is tilted back and forth, when the upper arm 4 comes into contact with the notch edge, the contact portion is bent upward and the fin shape made of rubber or soft vinyl chloride having elasticity enough to jump up is formed. An elastic cover member 6 for shielding the gap is provided in series. The means for connecting the elastic cover member 6 to the notch edge is heat caulking or any other means.

On the other hand, the seat back 2 is formed by covering the outer surface of a seat back pad 2a with a seat cover 2b. The lower portion of the seat back pad 2a on the upper arm 4 side faces upward during reclining operation as described above. A concave portion 7 is formed which can smoothly receive a bent portion of the elastic cover member 6 which has jumped up without complicated buckling deformation. In addition, this recess 7
As shown in FIG. 1, the lower portion of the seat back pad 2a may be formed in any shape, such as a rectangular shape or a triangular shape or a stepped shape as shown in FIGS. In addition, as shown in FIG. 7, the surface of the recessed portion 7 which is underfilled is reinforced by another member 8 such as a synthetic resin plate, or a seat back as shown in FIG. A gap is formed in the entire lower portion of the pad 2a, and a core material 9 is embedded in the seat cover 2b to secure the appearance quality, or the inside of the seat back pad 2a as shown in FIG. In other words, it is possible to arbitrarily design the elastic cover member 6 having a convex portion 10 formed at the lower portion so that the elastic cover member 6 that is bent and jumped up can be smoothly accommodated.

[0010] With such a construction, the reclining mechanism that normally supports the seat back 2 so as to be able to tilt back and forth is almost completely covered by the elastic cover member 6 so that the internal parts and the like are not exposed, and an excellent appearance is obtained. It shows quality. When the reclining mechanism is actuated, the elastic cover member 6 is bent upward along the upper arm 4 and jumps up. The jumping up portion is formed by the concave portion 7 formed at the lower portion of the seat back pad 2a. Due to its existence, it is received inside the concave portion 7 without complicated buckling deformation, so that the jumping portion does not bite into the parts of the reclining mechanism and is not dirty or damaged, and the jumping is performed smoothly. It will be.
As a result, no unreasonable deformation occurs in the elastic cover member 6, so that the elastic cover member 6 can be continuously used for a long time.

[0011]

As is clear from the above description, the present invention does not expose internal parts and the like regardless of the operation or non-operation of the reclining mechanism, and also reduces the gap between the seat back and the shield. Appearance quality can be improved, and when the reclining mechanism is activated,
The elastic cover member jumps upward along the upper arm and is received in the recess formed in the lower part of the seat back. It can be used for a long time without being stained or damaged. Therefore, the present invention greatly contributes to industrial development as an automotive seat that has eliminated the conventional problems.
