Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a seat reclining device.

The reclining device for automobile seats is the first
As shown in the figure, a lower bracket 1 fixed to the seat bottom and an upper bracket 2 fixed to the seat back are connected by a hinge shaft 3 to support the seat back so as to be able to swing back and forth with respect to the seat bottom. , since the hinge shaft part incorporates a reclining mechanism such as a large-diameter gear 4 and a locking pawl, the lower bracket 1 and the upper bracket 2
It is covered with a cover body 6 having a notch 5 in a range that allows the swinging of the body.

However, since the cover body 6 has a notch 5, the large-diameter gear 4 is visible, which impairs its aesthetic appearance, and the grease applied to the large-diameter gear 4 may stain the clothes of the occupant, or sand may enter the large-diameter gear 4. I was having a hard time.

The present invention has been made in view of the above-mentioned conventional problems, and includes a cover belt that is slidable along a guide formed inside the cover body and is connected to the above-mentioned upper bracket. By covering the notch, the notch can be covered at all times to improve the aesthetic appearance and prevent staining of clothes and damage to gears.

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

As shown in FIGS. 2 and 3, a lower bracket 1 fixed to the seat bottom 7 and an upper bracket 2 fixed to the seat back 8 are connected by a hinge shaft 3, and the lower bracket 1 is attached to a synthetic resin cover body. Covered by 9.

The cover body 9 has a flat plate-like surface 9a.
A semicircular rise 9b concentric with the hinge shaft 3, an inclined rise 9c that continues from a tangential direction to the upper side of the semicircular rise 9b, and a bottom rise 9d that continues from the inclined rise 9c and the lower side of the semicircular rise 9b. It consists of a box-shaped body with

As shown in FIG. 4, rectangular notches 10 are provided in the semicircular rises 9b and the inclined rises 9c of the cover body 9 in a range that allows the upper bracket 2 to swing.

As shown in FIG. 5, sliding grooves 11, 11 constituting a guide are formed on both inner edges of the notch 10, which are continuous with the semicircular rise 9b and the inclined rise 9c. A sheath-shaped sliding hole 12 is formed in the inclined rise 9c continuous with the grooves 11, 11.

On the other hand, a flexible cover belt 13 made of, for example, soft PVC is provided, and the cover belt 13 is inserted into the sliding groove 1.
1, 11 and the sliding hole 12 so as to be slidable, and the hook 13a at the tip is hooked to the side edge of the upper bracket 2.

The length of the cover belt 13 is set so that the rear end remains within the sliding hole 12 even when the upper bracket 2 swings to the fully reclined position, as shown in FIG.

With the above configuration, when the upper bracket 2 swings back and forth together with the seat back 8,
Since the cover belt 13 slides in the sliding grooves 11, 11 and the sliding hole 12 following the swinging of the upper bracket 2, the notch 10 is always covered by the cover belt 13.

As described above, the present invention includes a cover belt that is slidable along a guide formed inside the cover body, is connected to the upper bracket, and covers the notch with the cover belt. Since the notch is always covered, the aesthetic appearance is improved, and there are no accidents such as staining clothes with gear grease or damage due to sand getting into the gear.
