Description

Car seat with removable headrest

The present invention relates to an automobile seat, and more particularly, to an automobile seat equipped with a movable headrest for moving forward along an outer surface of the seat back to provide a forward view to a passenger of the rear seat.

The seat is divided into three parts, and the seat is generally installed in the interior of the vehicle in a structure in which the lower portion of the seat cushion is supported by the floor panel, which is the bottom structure of the vehicle.

In this seat, the headrest supports the head of the passenger to reduce the fatigue of the passenger when traveling for a long time, and to prevent the passenger's head from being backed up and injured in the event of an accident, and is supported by the rod at the top of the seat back. It can be lifted up and down to be used in accordance with the height of the passenger.

However, the above-described vehicle seats are inconvenient for passengers who ride on the rear seats by the headrests of the front seats even when the passengers do not ride on the front seats. In some cases, the headrest of the front seat is pulled out in order to alleviate this inconvenience, but in such a case, the safety of the passenger on the front seat becomes a problem.

Accordingly, an object of the present invention is to solve the above problems, to ensure safety for the passengers in the front seats, and to provide sufficient forward visibility to the passengers in the rear seats when there are no passengers in the front seats. An automobile seat is provided with a movable headrest that moves along the side of the seat back.

In addition, a spring 6 is installed inside the rod 5, and a fixing ball 7 is installed below the spring 6 to be supported downward by the elasticity of the spring 6. In addition, a protruding piece 9 is formed on the outer peripheral surface of the lower end of the rod 5 to prevent the rod 5 from being separated from the guide rail 4.

On the bottom surface of the upper seat back 1 of the guide rail 4, a pair of recesses 8 for holding the headrest 3 in a fixed state are spaced corresponding to the pair of rods 5, which are moving means. Is formed. When the fixing balls 7 are respectively accommodated in the recesses 8, the fixing balls 7 are not easily separated from the recesses 8 by the elasticity of the springs 6.

In the vehicle seat according to the present invention configured as described above, when the passenger boards the front seat, the headrest (3) is moved to the upper seat back (1) to the fixed ball (7) in the recess (8) By being accommodated, the headrest 3 can be fixed to support the passenger's head, thereby ensuring safety.
