DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat, and more particularly, to an anchor for fixing a child seat protruding from a rear portion of a seat frame, and a locking member provided on the child seat is engaged with the anchor. The present invention relates to a vehicle seat in which a child seat is fixed.

[0002]

2. Description of the Related Art Conventionally, when a child seat is mounted on a seat cushion of a vehicle seat, a seat belt is inserted through an insertion hole provided in a lower portion of the child seat with the seat back of the vehicle seat raised.
The child seat was fixed. Recently, in order to attach and fix the child seat simply and quickly, as shown in FIGS. 4 and 5, a reinforcing frame or a horizontal rod 3 having both ends fixed between the side frames 2 and 2 of the seat frame 1 is provided.
A pair of left and right anchors 5 for fixing the child seat 7 are projected upward and fixed by welding or the like.
In addition, as shown in FIG. 5, there is proposed a configuration in which a lock claw 9a of a lock member 9 provided on a child seat 7 is locked or unlocked. Also anchor 5
Has been proposed as a rotary type.

[0003]

However, when a pair of left and right anchors 5 project upward and are fixed to the reinforcing frame or the lateral rod 3 of the seat frame 1 of the conventional seat cushion by welding or the like, the child seat 7 is not provided with the same structure. When not in use, the anchor 5 gives the occupant a feeling of foreign matter or a hit, and when the anchor 5 is provided below the seat cushion, the child seat 7 cannot be easily and quickly attached. Further, when a reinforcing frame is separately attached to the seat frame 1, the number of parts increases, which has a disadvantage of increasing the cost. When the anchor 5 is of a rotating type, there is a possibility that the rotating shaft as a rotating shaft or the side frames 2 and 2 may be deformed due to a strong input in the left-right direction. If not locked, child seat 7
Cannot be easily and quickly attached, and there is a possibility that rattling may occur when the child seat 7 is mounted.

[0004] It is an object of the present invention to be able to easily and quickly attach a child seat, and to prevent the anchor or stopper from giving a occupant a sense of foreign matter or a hit when the child seat is not used, and to reduce the strength in the left-right direction. It is possible to easily and quickly perform the work of assembling the seat cushion, and there is no risk of rattling when the child seat is mounted, and the number of parts can be reduced. A sheet is provided.

[0005]

According to a first aspect of the present invention, there is provided a vehicle seat, wherein an anchor for fixing a child seat is provided at a rear portion of a seat frame so as to protrude, and the anchor is provided on the child seat. In the vehicle seat in which the lock member is locked to fix the child seat, a lateral rod is rotatably provided at a rear portion of the side frame of the seat frame, and the anchor projects forward from the lateral rod. A lock plate is fixed to an end of the horizontal rod, a latch inserted and locked in a lock groove of the lock plate is attached to the side frame, and a latch claw of the latch is normally locked in a lock direction by a lock spring. It is characterized by being biased to.

According to the first aspect of the present invention, a horizontal rod is rotatably provided at a rear portion of the side frame of the seat frame, and an anchor is provided on the horizontal rod so as to protrude forward, and a lock is provided at an end of the horizontal rod. The plate is fixed, and a latch inserted and locked in the lock groove of the lock plate is attached to the side frame, and the latch claw of the latch is normally urged in the lock direction by a lock spring, so that the child seat is anchored to the child seat. The anchor can be easily and quickly mounted in a protruding state projecting obliquely upward, there is no danger of rattling when the child seat is mounted, and the anchor is seated by making the storage state in which the anchor does not protrude when the child seat is not used. There is no fear of giving a foreign body feeling or a hit feeling to the person.

According to a second aspect of the present invention, the lock plate is urged by a reversing spring in a direction in which the anchor is housed downward.

According to the second aspect of the present invention, since the lock plate is urged by the reversing spring in a direction in which the anchor is housed downward, the pair of right and left anchors can be easily and quickly projected when the child seat is housed. And the pair of left and right anchors does not give the occupant a feeling of foreign matter or a sense of hit.

According to a third aspect of the present invention, in the vehicle seat, the lock plate also serves as a reinforcing plate.

According to the third aspect of the present invention, since the lock plate abuts on the seat frame and also serves as a reinforcing plate, even if there is a strong left-right input, the lock plate also serves as the reinforcing plate in the left-right direction. Can be improved, and there is no risk that the horizontal rod will be deformed or fall off, and that there will be no risk of rattling when the child seat is mounted.

According to a fourth aspect of the present invention, there is provided the vehicle seat, wherein a lifting strap is attached to the anchor.

According to the fourth aspect of the present invention, since the lifting strap is attached to the anchor, the latch claw of the latch can be inserted and latched in the lock groove of the lock plate only by pulling the strap, which is simple and quick. Thus, the child seat can be easily and quickly mounted in a protruding state in which the anchor projects obliquely upward.

According to a fifth aspect of the present invention, in the vehicle seat according to the first aspect, a release knob is attached to the latch, and the release knob is rotated against the bias of the lock spring to thereby lock the latch pawl and the lock plate. The locked state with the lock groove is released.

According to the fifth aspect of the present invention, the locked state between the latch claw of the latch and the lock groove of the lock plate is released by rotating the release knob against the bias of the lock spring. By operating the release knob when using the child seat, the locked state can be released easily and quickly, and the storage state can be achieved in which the anchor does not protrude.
