BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat chair having a movable armrest, and more particularly to a vehicle seat chair having a movable armrest adapted to be used from an adult to a child by adjusting the width according to the physical condition of the occupant.

In general, both sides of the seat chair is provided between the armrests to rest the occupant's arms to rest comfortably or restrain the body of the occupant to restrain the lateral movement of the occupant in the event of a vehicle crash, but to reduce or widen the armrest width There was a problem that would be uncomfortable in the case of the other passengers physical condition is not able.

Accordingly, the present invention has been invented to solve the above problems, the armrest is movable to expand or narrow the width of the armrest to the back of the seat chair can be used appropriately according to the physical condition of the occupant The object is to provide a car seat chair with an armrest.

The present invention for achieving the above object is provided with a hollow reinforcing pipe formed with insertion grooves at both ends in the open horizontal moving groove of the backrest constituting the seat chair is a moving shaft formed on the outer circumferential surface The armrest is provided with a body having a support end and a handle protruding out of the backrest so as to be hinged to the locking end and the backrest via a hinge pin so that the armrest is inserted into the insertion groove of the reinforcement pipe. While the hinge switch is provided, the body of the hinge switch has a structure in which the spring is provided to return to the original position by the elastic force.

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

FIG. 1 is a perspective view of a detachable combined perspective view of the movable armrest according to the present invention. The armrest 2 is provided on both sides of the backrest 1a provided with a seating chair 1 to form an open movable groove 1b. Is provided, but the armrest (2) is provided with a moving shaft (3) having a plurality of engaging grooves (3a) 90 degrees at a predetermined interval formed on the outer circumferential surface of about 180 °, built in the backrest (1a) It is inserted into the hollow reinforcing pipe (5) coupled to the bush (4) at both ends to use the coupling.

And both ends of the reinforcing pipe (5) is formed with the insertion groove (5a) to prevent the movement of the armrest (2), the hinge coupled to the backrest (1a) via the hinge pin (7) to adjust the position The switch 6 is inserted, and the hinge switch 6 has a body 6a fixed to the hinge pin 7 coupling support end 6d and a spring 8, and one end of the body 6a. A bent end 6c which is bent at 90 ° to the insertion groove 5a of the reinforcing pipe 5 and a backrest 1a which is bent at 90 ° to an opposite portion of the end of the reinforced pipe 6c to be operated by the occupant. It is made of a handle (6d) protruding outward. Also, as shown in FIG. 2, armrests 2 are provided on both sides of the backrest 1a of the magnet chair 1, and the handle 6b of the operation switch 6 is located above the armrest 2. While protruding to the outside, the base member 1c is added to have a moving groove 1b formed across the backrest 1a so that the armrest 2 can be moved.

Therefore, when the armrest 2 is placed on both sides of the backrest 1a of the seating chair 1, the armrest of a large passenger, such as an adult, or the side of the occupant's body is prevented when the vehicle crashes. If the body is a small occupant as described above, when the handle 6b of the operation switch 6 provided on the side of the backrest 1a is pressed, the moving shaft coupled to the reinforcement pipe 5 clockwise through the hinge pin 7 ( As the locking end 6c fitted into the locking groove 3a of 3) is rotated upward, the spring 8 is compressed while being pulled out.

Subsequently, the occupant moves the armrest 2 inward along the opening groove 1b of the backrest 1a, thereby reinforcing the locking groove 3a formed in the moving shaft 3 of the armrest 2. When the knob 6b is positioned in accordance with the insertion groove 5a of the 5, the hinge switch 6 is rotated counterclockwise by the elastic force of the compressed spring 8, and the reinforcement pipe 5 It is coupled to the locking groove (3a) of the moving shaft (3) through the insertion groove (5a) of the) is to be fixed.

In addition, when the armrest 2 is not used, when the armrest 2 is lowered above or below the backrest 1a of the seat chair 1, the moving shaft 3 of the armrest 2 is lowered. The armrest 2 can be attached to the side of the backrest 1a by being moved upwards or downwards at an angle of 90 ° along the locking grooves 3a of the 180 ° angle formed on the backrest 1a. The opened moving groove 1b is hidden by the shade 1c and becomes invisible.

As described above, according to the present invention, the armrests provided on both sides of the seat chair are adjustable in width according to the physical condition of the occupant, so that all of them can be used without any protective equipment from children to adults.
