Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to seats for buses, railway vehicles, ships, etc., and particularly to vehicle seats equipped with a reclining device that allows the seat back to be folded backwards.

(Prior Art) In recent years, many vehicle seats used in buses, railway vehicles, ships, etc. are equipped with reclining devices that allow the seat back to be tilted backwards by operating a lever or switch. ing. By the way, in this type of seat, a head rest is integrally provided at the top of the seat back, and its mounting position is also set at a height where the head can properly rest in the normal sitting position, that is, with the seat back upright. is fixed.

(Problem to be solved by the invention) However, when the seat bag is tilted backwards using a reclining device, there is a misalignment between the axis of rotation of the back of the person and the axis of rotation of the seat bag, so that the head is tilted backwards. Unable to follow headrest,
There was a problem with it slipping down from its proper position or hanging down.

This invention was devised in view of the above-mentioned deficiencies in the prior art, and its purpose is to provide a vehicle for which the head can always be placed in the proper position against the headrest, regardless of the inclination of the seat back. It is intended to provide seats.

(Means for Solving the Problems) Therefore, the vehicle seat according to the present invention has the following configuration in order to achieve the above object. That is, in a vehicle seat whose seat back can be reclined rearward by a reclining device, the seat back and the headrest are provided separately. A guide belt is stretched longitudinally along the upper front surface of the seat bag, while a belt loop through which the guide belt is inserted is provided on the back surface of the headrest. Therefore, the headrest is attached to the seat bag so as to be movable in its height direction via the stretched guide belt and the belt loop through which the guide belt is inserted.

Further, a portion of the head rest is provided with a male or female engaging element of a hook-and-loop fastener, while a portion of the head rest cover made of a disposable material is easily engaged with the engaging element, and is easily engaged with the engaging element. A female or male engagement element is provided for disengagement. Thus, these two elements are engaged to attach the headrest cover to the headrest.

(Function) First, the seat back is erected and the headrest is moved up and down along the tensioned guide belt to adjust its height position so that the headrest properly hits the head of the seated person. In this case, the headrest does not slip off due to frictional resistance with the seat bag, but is moved and fixed at an arbitrary height position. When the seatback is tilted backwards via the reclining device while resting the head on the headrest, the weight of the head is applied to the headrest as the head falls. Therefore, the headrest is attached to the seat back so as to be movable in its height direction via the stretched guide belt and the belt loop through which the guide belt is inserted.
By receiving the weight of the head, it moves to follow the lowering of the head while resisting the frictional resistance.

It is also possible to manually lower the headrest to the lowest position in advance, or to adjust the headrest to an arbitrary position by hand.

(Example) Hereinafter, an example of this invention will be described based on FIGS. 1 to 3.

Seat 1 is equipped with an attached reclining device.
The seat bag 2 can be folded backwards, and especially when a vehicle such as a bus runs at night, the seat bag 2 can be laid almost sideways and used as a bed. A head rest 3 is provided on the upper part of the seat bag 2. This headrest 3 is separate from the seat bag 2, and is not fixed to the seat bag 2, but is movable in the height direction thereof.

As a structure for attaching the headrest 3 in a movable manner, for example, there is a method of moving it along a belt. That is, the seat bag 2 is provided with a guide belt 4 extending vertically along the upper front surface thereof. This guide belt 4 is attached with a slight tension, and one end is fixed to the upper surface of the seat bag 2 by sewing, and the other end is attached to the front surface of the seat bag 2 with a hook H.
It is removably fixed via a locking device such as. On the other hand, a belt loop 5 is provided on the back side of the headrest 3, through which the guide belt 4 is inserted.
Therefore, the headrest 3 is attached to the seat back 2 via the guide belt 4 so as to be movable in the height direction.

Further, a male engaging element 7 of a hook-and-loop fastener is provided on a part of the head rest 3, for example, on the back surface thereof, so that a head rest cover 6 covering the head rest 3 can be attached. On the other hand, the headrest cover 6 is molded from a relatively inexpensive disposable material such as non-woven fabric or paper, and has one end of the back surface that is a part of the headrest cover 6, which easily engages with the engagement element 7. A female engagement element 8 is provided for disengagement. As the male engagement element 7, for example, a well-known dense hook is employed. Further, as the female engaging element 8, a material made of densely grown loop-like or fried-like fibers, which can be engaged with the densely-woven hook, is used. Therefore, these elements 7 and 8 are engaged, and the headrest cover 6 is attached to the headrest 3. However,
A female engaging element of a hook-and-loop fastener may be provided on the head rest 3 side, and a male engaging element may be provided on the head rest cover 6 side.

Now, when using this vehicle seat, operate as follows. First, seat bag 2
The height position of the headrest 3 is adjusted so that it properly hits the head of the seated person in an upright state. Adjustment is performed by moving the headrest 3 up and down along the guide belt 4. The guide belt 4 is
As mentioned above, the installation was a little tense. Therefore, the headrest 3 does not slip off due to frictional resistance with the seat bag 2, and can be moved and fixed at any height position.

Next, with your head resting on the headrest 3, the seatback 2 is lowered via the reclining device.
When the headrest 3 is tilted backward, the weight of the head is added to the headrest 3 as the head falls. Therefore, the headrest 3 resists the frictional resistance by receiving the weight of the head, and automatically moves to the appropriate position following the downward movement of the head, as shown by arrow A in FIG. do.

Of course, it is also possible to use the seat bag 2 alone without resting the head on the head rest 3, and move the head rest 3 to the appropriate position by visual estimation.

In addition, you can manually lower the headrest 3 to the lowest position in advance, or manually lower the headrest 3.
It is also extremely easy to adjust to any desired position.

In order to attach the headrest cover 6 to the headrest 3, the male engagement element 7 and the female engagement element 8 provided thereon may be brought face to face with each other and pressed lightly from above. After used,
The headrest cover 6 is removed by peeling off the female engaging element 8 from the male engaging element 7, and is discarded as trash without being reused.

(Effects of the invention) This invention has the above configuration and has the following effects.

1. According to the vehicle seat according to claim 1, the headrest is attached to the seat back so as to be movable in its height direction via the stretched guide belt and the belt loop through which the guide belt is inserted. When the seatback is upright, the headrest does not slip off due to frictional resistance with the seatback, but is moved to a desired height position and fixed, and the seatback can be tilted backwards with the head resting on the headrest. Then, the headrest moves to follow the lowering of the head while resisting the frictional resistance by receiving the weight of the head. Thereby,
The mounting height position of the headrest can be arbitrarily changed depending on the inclination of the seat bag. Therefore, regardless of the inclination of the seat back, the head can always be placed in an appropriate position relative to the headrest.

2. Also, in the vehicle seat according to claim 2, since the headrest cover is attached to the headrest by a hook-and-loop fastener method,
This prevents the headrest from getting dirty and also makes it easy to replace and remove the seat. Moreover, since this headrest cover is molded from a disposable material and is not reused after use, it is both sanitary and inexpensive.
