Description

Lever of seat reclining for vehicle}

The present invention relates to a seat reclining lever for an automobile, and more particularly, to an improvement of a lever for operating a reclining part for adjusting the seat back of an automobile in a forward and backward direction to fit a body of a rider.

The seat of the car is to maintain the occupant's posture.It is a separator type seat provided in the driver's seat and the passenger seat so that only one person can be seated and a bench type seat that is provided at the back of the passenger compartment so that multiple people can be seated at the same time. Are distinguished.

In the case of the separator type seats provided in the double driver's seat and passenger's seat, the reclining device that allows the backrest to be angled forward and backward to suit the driver's and occupant's body shape so as to maintain a proper posture for driving or to allow the passenger to relax. It is provided.

The reclining apparatus is configured to be angle-adjusted by the back of the seat by operating a lever protruding laterally mounted on the connection between the cushion frame and the seat back frame constituting the seat of the vehicle.

Looking at it through FIG. 1;

The seat rail 30 of the vehicle is composed of a lower rail 32 and an upper rail 33 having a locking means 31, and a seat frame 34 is fixed above the upper rail 33.

A rotation shaft 35 and a link assembly 36 are provided between the seat frame 34 and the seat frame 34 to adjust the height and the height of the seat frame. Recliner 40 for angle adjustment in the rearward direction is provided.

The recliner is angled in the front and rear direction with respect to the seat rail by the operation of the reclining lever can be adjusted according to the body shape and driving habits of the rider.

The reclining lever 1 to which the prior art is applied has an operating plate 3 having a fixing hole 2 formed at the center thereof so as to connect a cam for lock gear control while fixing to the seat frame as shown in FIG. 5. do.

Below the operating plate 3, a spring connector 4 having a spring hole is formed so as to connect a return spring for returning the reclining lever 1 to its original position.

In front of the operating plate 3, a handle 7 having one bent portion 5 bent in an outward direction and two bent portions 6 bent forward from the first bent portion 5 is protruded. It is composed.

The first bent portion (5) is formed by forming an embossing (8) protruding outward to prevent deformation against bending.

The conventional lever as described above has rigidity with respect to the force generated during the operation by the embossing formed in the bent portion and the first bending portion during normal operation, that is, when operating in the up, down direction of the seat rail.

However, when an external force is applied to the outside of the seat rail, since there is no special reinforcement measure, there is a problem in that normal operation is impossible because it is easily bent or deformed.

As described above, since the lever is easily deformed in the outward direction of the seat rail, there are various problems such as deteriorating the quality of the whole seat and significantly affecting durability and safety.

Therefore, the present invention is designed to solve the above problems, and improves the reclining lever so that the lever operates normally in the up and down directions, and also prevents deformation such as bending when malfunctioning in the side direction of the seat rail. The purpose is to contribute to the improvement of durability.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operation of the present invention for achieving the above object.

1 is a perspective view of an automobile seat rail shown to explain the present invention, FIG. 2 is a partial fractured front view of the main portion of the vehicle seat reclining lever to which the technology of the present invention is mounted, and FIG. 4 is a perspective view illustrating an automobile seat reclining lever to which the technique of the present invention is applied, and FIG. 4 will be described together as an excerpt sectional view taken along line A-A of the automobile seat reclining lever applied to FIG.

The seat rail 30 of the vehicle is composed of a lower rail 32 and an upper rail 33 having a locking means 31, and a seat frame 34 is fixed above the upper rail 33.

A rotation shaft 35 and a link assembly 36 are provided between the seat frame 34 and the seat frame 34 to adjust the height and the height of the seat frame. Recliner 40 for angle adjustment in the rearward direction is provided.

The recliner 40 is a reclining plate 41 for fixing the seat back to the rear end of the seat frame 34 which is fixed above the seat rail 30 is fixed to the hinge pin 42.

A lock gear that is connected to and separated from the sector gear 43 by a cam 46 connected to the lever 45 fixed to the seat frame 34 by fixing the sector gear 43 inside the reclining plate 41. 47) are combined.

On the outside of the lever 45 and the reclining plate 41, the holding plate 48 is finished, and on the outside of the holding plate 48, the return spring 50 for returning the reclined seatback is hinge pin 42 and It is installed between the engaging pins 51 fixed to the reclining plate 41.

A lever spring 55 is provided between the holding plate 48 and the lever 45 to assist the return of the lever 45 after the operation.

In the present invention, the lever 45 of the recliner 40 may be improved to operate the lever 45 for reclining, as well as to force the lever 45 to the outside of the seat rail 30 by misoperation. It is characterized by making it easy to prevent deformation.

In the present invention for this purpose;

To the front of the operating plate 61 and the operating plate 61 having a fixing hole 60 in the center to connect the cam 46 for controlling the lock gear 47 while being fixed to the seat frame 34 1, 2nd bent portion (65,66) formed between the protruding handle 62 is improved.

That is, the two bent portions 66 are formed by forming the embossed 68 in the opposite direction to the embossed 67 protruding outward from the one bent portion 65 so as to prevent deformation against bending. Make sure to get rigidity.

In addition, the upper surface of the two bent portion 66 further forms a reinforcing rib 70 integrally with the bent portion 66 so as to maintain sufficient rigidity when the handle 62 is forced outward.

Of course, the reinforcing ribs 71 may be further integrally formed on the bottom surface as well as the upper surface of the two bent portions 66.

The present invention as described above;

In the case of reclining the seatback, when the lever 45 is held and pulled upward, the sector gear 43 is released from the lock gear 47 so that the seatback can move freely, and the sector is released by releasing the lever 45. The gear 43 is brought into contact with the lock gear 47, thereby preventing the seatback from moving.

Since the reclining is the same as the conventional reclining method, a detailed description thereof will be omitted and an intensive description will be given with respect to the lever 45.

As described above, when the lever 45 is operated for reclining, only the upper and lower directions move.

That is, when pulling upward, a pulling force is applied by the user, and when the lever 45 is released, the lever spring 55 returns to the original position.

When the lever 45 is operated for reclining as described above, the embossing 67 formed on the one bent portion 65 between the operating plate 61 and the handle 62 and the embossed portion 68 formed on the two bent portions 66. Stiffness is ensured.

The phenomenon in which the handle 62 of the lever 45 is deformed even when the user incorrectly pulls the lever 45 laterally (outer direction of the seat) without pulling up the lever 45 by an incorrect operation is prevented.

This is because the rigidity is ensured by the reinforcing ribs 70 and 71 formed integrally with the bent portions 66 on the upper and lower two bent portions 65 and 66 between the handle 62 and the operating plate 61. will be.

The present invention, as described above, improves the reclining lever, and the lever can be operated normally in the up and down directions as well as prevents deformation such as bending even when malfunctioning in the lateral direction of the seat rail. The effect can be obtained.
