Description

[Detailed Description of the Invention] This invention relates to an improvement of a reclining device for an automobile seat.

Conventionally, as shown in FIG. 1, the above-mentioned reclining device has a plurality of engagement grooves 4, . 4 is fixed, and a striker 7 attached to the frame 6 of the seat bag 3 is inserted into one of the engagement grooves 4, . By engaging and disengaging the seat back 3
A device that adjusts the tilting position of the
171402) has been proposed.

As shown in Figs. 1 and 2, when the seat back 3 is folded forward, the sharp engagement grooves 4,..., 4 of the sector member 5 are exposed, so there is a risk that your hands or body may come into contact with the sharp corners. It was also dangerous.

This idea was made in view of the above-mentioned conventional problems.The striker is formed of wire into a roughly U-shape, and the shafts at both ends are pivotally attached to the seat back frame, making it simple in structure. At the same time as improving durability, the sector member is formed with a protrusion extending upward from the engagement groove, and a cover member is provided to expose the engagement portion of the sector member and cover the sector member to avoid sharp edges. It is designed to prevent hands etc. from touching the engagement groove.

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

As shown in FIGS. 3 and 4, the frame 11 of the seat bag 10 is attached to the vehicle body 1 with bolts 29, 2.
The lock frame 13 has a structure in which a portion corresponding to the sector member 12 fixed at the lock frame 13 is connected to the lock frame 13, and a striker 15 formed in a roughly U-shape from a wire rod is installed in a shaft hole 14 bored in one side wall 13a of the lock frame 13. A bearing boss 16 that rotatably supports the shaft portion 15a on one side is fitted, and a torsion coil spring 17 is fitted to the shaft portion 15b on the other side of the striker 15, and the shaft portion 15b on the other side is rotatably supported. Bearing boss 1 supported on
A lock plate 20 is fitted to the bearing boss 18, and the lock plate 20 is connected to the other side wall 13b of the lock frame 13 by screws 23, 2.
Fix it integrally with step 3.

Therefore, the striker 15
The striker 1 is supported at both ends by the striker 3 and the lock plate 20, and is swingably supported by the striker 1.
A torsion coil spring 17, which is latched to a striker auxiliary piece 24 integral with the striker 5 and whose other end is latched to the lock plate 20, biases the sector member 12 in the direction of engagement with the engagement grooves 12a, . . . , 12a. be done.

The striker auxiliary piece 24 receives an engagement hole 27 that engages a bent portion 26 at the lower end of a rod 25 that is linked to a manual knob (not shown).

On the other hand, as shown in FIGS. 5 and 6, the sector member 12 is formed by bending a metal plate into a roughly L-shape, and its base 28 is fixed to the vehicle body 1 with bolts 29.

The sector member 12 has a protrusion 3 that protrudes substantially parallel to the support portion 30 in which the engagement groove 12a is formed.
1 to prevent hands etc. from touching the engagement groove 12a.

In addition, a glove-shaped synthetic resin cover 32 that can be inserted from the tip side is provided on the protruding portion 31 and the supporting portion 30 other than the portion of the engaging groove 12a (engaging portion), as shown in FIG. When inserting the cover 32, the small hole 3 formed in the side wall of the support portion of the cover 32
3 is engaged with and held by a punched-out portion 34 punched out from the support portion 30.

Note that a recess 35 is provided at the tip of the support portion 30,
Providing the positioning protrusion 36 within the support portion of the cover 32 prevents the support portion of the cover 32 from being turned over and ensures reliable positioning during insertion.

A stopper portion 37 is provided at the lower edge of the lock plate 20 and bent toward the lower end of the sector member 12 to prevent the sector member 12 from escaping downward.

If the reclining device is configured as described above, when the lifting operation of the manual knob is released, the rod 25 will be in the lowered position, and the striker 15 will be in the state where it is engaged with one of the engagement grooves 12a of the sector member 12. When the operating knob is pulled up and the rod 25 is raised, the lower end bent portion 26 touches the striker auxiliary piece 24.
The striker 15 is smoothly swung in the detachment direction.

Then, when the seat bag 10 is swung forward in the forward tilting direction while the hand-operated knob is pulled up, the seat bag 10 is tilted forward as shown in FIG.

When the seat bag 10 is folded forward, the engaging groove 12a of the sector member 12 is surrounded by the protrusion 31 of the sector member 12, so there is no risk of your hands touching it.Moreover, the outer periphery of the sector member 12 is made of synthetic resin. It is safe because it is covered with the cover 32.

Although the protruding portion 31 of the sector member 12 in the above embodiment is integrated, the protruding member 38 is attached to the sector member 12 by a pin 39 as shown in FIGS.
Hinge with
It may be configured such that it is biased towards the 2a side and swings against the spring force when the striker 15 is engaged.

Further, as shown in FIG. 10, a protruding member 41 is supported on the sector member 12 with a pin 42 so as to be slidable, and is biased toward the tip side with a coil spring 43 to resist the spring force when the striker 15 is engaged. It may also be configured to slide backward.

In addition, pull up the manual operation knob and set seat back 1.
0 backwards and release the lifting operation of the manual knob when any striker 15 corresponds to the engagement groove 12a of the sector member 12, it can be locked at a rearward tilted position from the above position, The seat back 10 can be adjusted to tilt backward, and the tilt of the seat back 10 can also be adjusted from a backward tilted position to a forward tilted position.

As is clear from the above explanation, this invention has a striker formed of wire into a roughly U-shape and pivoted to the frame of the seat bag with hinges on both sides to allow it to swing. This method is extremely simple, reduces costs, and improves durability. On the other hand, the sector member is formed with a protruding portion that protrudes above the locking groove, the engaging portion of the sector member is exposed, and a cover member is provided to cover the sector member. Therefore, even when the seat bag is folded forward, it is safe because hands and body do not touch the locking groove.
