Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement in the rear cover structure of an automobile seat.

(Prior Art) Conventionally, as shown in FIGS. 5 and 6, there has been provided an automobile seat 3 in which a seat back 2 is connected to a seat cushion 1 by a nutcle (not shown) so as to be tiltable forward and backward.
In the above, when the seat back 2 is tilted forward, the knuckle is visible from the rear, so the seat side cover 4 is turned to the rear and serves as a rear cover 4a for the knuckle.

(Problem to be solved by the invention) However, when seatback 2 is tilted backwards (6th
Since it is necessary to secure a gap t (see the two-dot chain line in the figure), the knuckles can still be seen through this gap t, resulting in a poor appearance.

The present invention was developed in order to solve the above problem, and the purpose of this invention is to improve the appearance of the above-mentioned automobile seat by preventing the nutcle from being completely visible through the gap when the seat back is tilted forward. That is.

(Means for Solving the Problems) Therefore, the present invention provides an automobile seat in which a seat back is connected to a seat cushion with a nut so that it can be tilted back and forth, and the upper part of the rear cover of the nut that is attached to the seat cushion is A lower cover of the seat bag is integrally formed so as to be able to swing back and forth, and the lower cover is urged by a return spring so as to contact the seat bag.

(Operations and Effects of the Invention) In the present invention, the lower cover of the seat bag is integrally molded on the upper part of the rear cover of the Knuckle so that it can swing back and forth, and the lower cover is urged to contact the seat bag by a return spring. It is something.

Therefore, since the rear cover covers the rear part of the nut and the lower cover covers the gap, when the seatback is tilted forward, the nut is completely hidden from view through the gap, improving the appearance.

Further, when the seat back is tilted backward, the lower cover is pushed by the seat back and swings backward, so there is no problem in the forward tilting operation of the seat back, and there is no risk of the lower cover being damaged due to the backward tilt of the seat back.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the automobile seat 10 is constructed by connecting a seat back 12 to a seat cushion 11 with a knuckle (not shown) so as to be tiltable forward and backward.

The seat cushion 11 includes a rear cover 13 of a knuckle formed with a U-shaped cross section along the rear protrusion 12a of the seat back 12 (see FIG. 3).
is fixed with bolts and nuts 17.

The rear cover 13 is made of synthetic resin and is set at a height that ensures a gap t when the seat back 12 is tilted backward (see the two-dot chain line in FIG. 2).

A seat back 1 is provided on the upper part of the rear cover 13.
A lower cover 14 having a U-shaped cross section along the rear protrusion 12a of 2 is integrally formed so as to be swingable back and forth.

The rear cover 13 covers the lower part of the rear protrusion 12a of the seat back 12 as well as the gap t.

A thin hinge part 15 cut into a V-shape in the vehicle width direction is integrally formed between the lower part of the lower cover 14 and the upper part of the rear cover 13.
5 allows the lower cover to swing back and forth with respect to the rear cover 13.

A spring locking portion 14a as shown in FIG. 4 is formed on the inner surface of the lower cover 14, and
The above bolt/nut 17 has a return spring 16.
The upper free ends of the return springs 16 are locked to the locking portions 14a of the lower cover 14.

This return spring 16 allows the lower cover 1
4 is urged into contact with the seat bag 12.

With the above configuration, the rear cover 13 covers the rear part of the knuckle, the lower cover 14 covers the gap t, and when the seat back 12 is tilted forward, the lower cover 14 is attached to the return spring 16. Since it follows the seat back 12 with force, the gap t is always covered by the lower cover 14, and the knuckle is completely hidden from the gap t.

On the other hand, when the seat back 12 is tilted backward, the lower cover 14 is pushed by the seat back 12 and swings backward against the biasing force of the return spring 16 (second
(see the two-dot chain line in the figure), there is no problem in the backward tilting operation of the seat bag 12.

When the seat bag 12 is raised from this state, the lower cover 14 follows the seat bag 12 by the biasing force of the return spring 16, so that the gap t is guaranteed to be covered.
