Abstract

(57) [Abstract] [Purpose] To prevent the infant C sitting on the seat cushion 1 from falling and to facilitate the care of the infant C. [Structure] Armrests 3 and 4 are pivotally attached to the middle portions of both sides of a seatback 2 in a standing or forwardly tilted position so that they can be locked. Then, the base end of the head restraint 5, which extends horizontally at a right angle to the arm rest 4, is fixed to the tip of the one arm rest 4.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a vehicle seat suitable for a passenger seat of a passenger car.

[0002]

[Prior Art]

 Conventionally, when an infant rides in a car, an adult holds it or a child seat is used. Whenever a child seat was used, it was tied to the vehicle seat, and the infant was tied to the child seat.

[0003]

[Problems to be solved by the device]

 The conventional child seat has a problem that it is troublesome because it must be secured to the vehicle seat each time it is used. In addition, there is a problem that it is difficult for an infant to be cared for because it is bound to a child seat.

[0004]

[Means for Solving the Problems]

 The present invention has been proposed to solve the above problems, and the gist of the present invention is to attach the base ends of armrests rotatably around a horizontal axis to the middle steps on both sides of the seatback. Each armrest is equipped with a lock mechanism that locks it in the upright position and in the forward tilted position, and extends horizontally at a right angle to the tip of one of the armrests, and is positioned above the seatback when the armrest is erected. The vehicle seat is characterized in that, when both armrests are tilted forward, the base ends of the head restraints are fixed so that the front ends of the two armrests are close to the front ends of the other armrests.

[0005]

[Action]

 Since the present invention has the above configuration, if the pair of armrests are locked in the forward position, the infant falls by surrounding the infant seated on the seat cushion with the pair of armrests and the head restraint. Can be prevented.

[0006]

【Example】

 One embodiment of the present invention is shown in FIGS. In FIG. 1, 1 is a seat cushion, 2 is a seat back, 3 and 4 are arm rests, and 5 is a head restraint. The base ends of the armrests 3 and 4 are rotatably attached to the middle stages on both sides of the seatback 2 about a horizontal axis, and are placed in the standing position shown by the solid line and the forward position shown by the chain double-dashed line by the locking mechanism shown in FIG. It is designed to be locked.

One end of a head restraint 5 that extends horizontally at a right angle to the armrest 4 is fixed to the tip of the armrest 4, and they are L-shaped as a whole. The headless train 5 is located above the seat back 2 when the armrest 4 is erected, and supports the back of the head when an adult sits on the seat cushion 1. On the other hand, when the armrests 3 and 4 are in the forward tilted position, as shown by the two-dot chain line in the figure, they are spaced apart from each other and are substantially horizontal, and the head restraint 5 is spaced apart from the seat back 2. The ends of the armrests 3 are parallel to each other and are horizontal, and the ends thereof are close to the ends of the armrests 3.

Then, when the infant C is seated on the seat cushion 1, if the armrests 3 and 4 are moved forward, the infant C is surrounded by the armrests 3 and 4 and the head restraint 5, and the infant C is seated on the seat cushion 1. You can prevent them from falling off. Further, when taking care of the infant C, if only the armrest 3 on the driver's side is raised, the infant C can be easily taken care of while sitting in the driver's seat. Similarly, when the luggage is placed on the seat cushion 1, the luggage can be prevented from falling by setting the armrests 3 and 4 to the forward position, and the luggage can be taken in and out by raising the armrest 3. It can be done easily from the driver's seat. Further, even when an adult is seated on this seat, the armrests 3 and 4 can be set to the forward position, and in this case, the armrests 3 and 4 can naturally exhibit their original functions. is there.

FIG. 2 shows an example of the lock mechanism. A lock plate 11 is integrated with the mounting bracket 12 and is fixed to the seat back 2 by fastening the mounting bracket 12 to a bracket 14 fixed to a frame 13 of the seat back 2 with a screw or the like. A lock pin 16 is fixed to the frame 17 of the armrests 3 and 4 via a bracket 18. A coil spring 20 is arranged around a cylinder 19 fixed to the frame 17, the shaft 21 implanted in the lock plate 11 is penetrated into the cylinder 19, and the shaft 21 is attached to a screw hole 22 formed in the tip end surface of the cylinder. The screw 23 is screwed in. Thus, the frame 17 rotates about the shaft 21, and the rotation of the frame 17 is stopped when the lock pin 16 is fitted into the lock hole 24 or 25 formed in the lock plate 11.

[0010]

[Effect of the device]

 In the present invention, the base ends of the armrests are rotatably attached to the middle tiers of both sides of the seat back about a horizontal axis, and the base end of a head restraint extending horizontally at a right angle is attached to the front end of one of the armrests. Since they are fixed, the pair of armrests can be locked in the forward position to prevent the infant from falling by surrounding the infant seated on the seat cushion with the pair of armrests and the headless train. Then, by raising the other armrest, it is possible to easily take care of the infant. As a result, it is not necessary to tie the child seat to the vehicle seat as in the conventional case, and it is not necessary to untie the child seat and move it from the child seat to care for the child.
