Leg support device of seat for car

The present invention relates to a leg support device for a car seat, and more particularly, to a leg support device for a car seat that is rotatably installed at the front end of a seat cushion to provide comfort by supporting the legs of a passenger when necessary. it's about

In general, when sitting on the seat, you can feel more comfortable if you spread your legs and place them on a separate legrest. Therefore, in recent years, by installing a leg support device in front of the cushion part of the sofa to support the calf part when the user wants it, the convenience and comfort of the sofa are doubled.

For the same purpose, leg support devices have been installed in the rear seats of vehicles, especially luxury passenger cars. However, the vehicle does not stop and repeatedly turns left and right while driving. At this time, the legs fall due to the turning inertia in both directions of the leg support cushion, which impairs convenience and comfort.

Therefore, as in Patent Registration No. 10-0821101 (registered on Apr. 2, 2008, Hanilhwa Co., Ltd., vehicle seat leg rest), guide cushions are installed at both ends of the main support cushion, and when necessary, the guide cushion is rotated to rotate the main support cushion. By protruding vertically upward from the end of the support cushion, it is prevented that the passenger's legs are separated from the main support cushion when the vehicle is turning.

However, in the conventional leg support device as described above, a pipe member (a screw is formed on the inner circumferential surface) is installed through the main support cushion, and a fixing member (a type of bolt) penetrating the guide cushion to the pipe member is screwed. made of structure

Therefore, the guide cushion rotates upward around the pipe member on a plane perpendicular to the width direction line of the main support cushion to form a leg support surface perpendicular to the plane of the main support cushion, or rotates downward to the original position in that state. It returns to the state of forming the same plane as the plane of the main support cushion.

However, the conventional guide cushion consists of a structure that maintains the used state rotated upward by the frictional force generated between the main support cushion and the main support cushion. And, when such a phenomenon occurred, it was not possible to support the passenger's legs so as not to depart from the main support cushion.

In addition, since the guide cushion is connected to the main support cushion with Velcro tape and maintained in the storage state when not in use, its position is not maintained firmly, so it is rotated by running vibration, etc. to form exactly the same plane as the main support cushion. It became a factor which deteriorated the external appearance of a sheet|seat by protruding by a predetermined amount without being able to do it.

In addition, in the case of a large passenger, there are cases where only the width of the main support cushion is insufficient to support the two legs of the passenger. There was a problem that the passenger did not fully enjoy the convenience of the leg support device and had to endure the inconvenience.

Accordingly, the present invention has been devised to solve the above problems, and by being able to firmly maintain the use position and the storage position, it is possible to prevent the passenger's legs from being separated when the vehicle is turning and to prevent deterioration of the appearance of the seat in the storage state. It is an object of the present invention to provide a leg support device for a car seat that can support a leg normally even for a large passenger by being able to increase the width direction area of the leg support surface.

The present invention for achieving the above object, a main plate rotatably installed on the cushion frame of the seat through a lever assembly, a wing plate rotatably installed through the longitudinal hinge shafts of both ends of the main plate as a medium, It includes a position adjusting means for adjusting the rotational position of the wing plate.

Mounting portions are protruded from upper and lower portions of both ends of the main plate, and mounting brackets having hinge shaft holes are mounted on each mounting portion, and hinge shaft holes are formed at the base end of the wing plate, and the hinge shaft hole and the wing of the mounting bracket. The hinge shaft is inserted and installed through the hinge shaft hole of the plate.

The positioning means includes a fixing pin hole formed in the mounting portion of the main plate, a fixing pin hole of the mounting bracket formed at a position facing the fixing pin hole of the mounting portion, and a plurality of formed on the same radius around the hinge shaft hole of the wing plate. and a fixing pin inserted into the positioning hole by passing through the fixing pin holes.

The fixing pin hole of the mounting bracket is formed to be spaced apart from the hinge shaft hole toward the front side of the mounting plate, and the distance between the hinge shaft hole and the fixing pin hole of the mounting bracket is the same as the distance between the hinge shaft hole and the positioning hole of the wing plate.

When the fixing pin is inserted into the positioning hole, a first positioning hole for putting the wing plate in a folded storage state toward the rear surface of the main plate, and a second positioning adjustment for putting the wing plate in a flat first use state with the main plate It may include a hole and a third positioning hole for placing the wing plate in an upright state with respect to the main plate.

A tension spring for always rotating the wing plate toward the front side of the main plate may be installed on the hinge shaft.

A return spring for returning the fixing pin to its original position may be installed on the mounting portion of the main plate.

According to the present invention as described above, there is provided a leg support device in which the storage state of the wing plate and the positions of the first use state and the second use state are firmly fixed and maintained by the fixing pins.

Accordingly, deterioration in appearance due to the position error in the storage state of the wing plate is prevented, and deterioration in performance due to the position error in the use state is prevented. In particular, since the state in which the wing plate is erected with respect to the main plate (the second use state) is accurately and firmly maintained, it is possible to reliably prevent the disengagement of the passenger's legs from the main plate when the vehicle is turning.

In addition, in the leg support device according to the present invention, the wing plates are spread at both ends of the main plate so that the support area of the main plate can be expanded, so that even passengers with a large body can support their legs more comfortably without feeling narrow.
