Description

[0001]
BACKGROUND OF THE INVENTION
The present invention mainly relates to a headrest cover that is attached to a headrest of an automobile seat for preventing dirt, and relates to an improved headrest cover for an automobile seat that can reduce a burden on the head and neck in a sitting posture of an occupant. is there.
[0002]
[Prior art]
In general, as shown in FIG. 13, the automobile seat has a headrest H so that the occupant A's rear head is positioned in the front with a gap W of about 10 cm between the back of the occupant A and the headrest H in a normal sitting posture. The headrest stay S is constructed by being installed on the upper side of the seat back B.
[0003]
In the sitting position, the head and neck of the occupant are usually not supported by the headrest from the rear side. Although it is not so much trouble if it is a short time driving in this sitting posture, if it is a long time driving, a burden is applied to the head and neck of the occupant, giving a feeling of fatigue. In order to reduce the burden, on general roads, it is possible to hang the head on the headrest for a while when stopping at a signal. However, it is difficult to see the front in a posture with the head resting on the headrest, so this is not possible when traveling on a highway.
[0004]
2. Description of the Related Art Conventionally, as a headrest equipment for causing a seated occupant's support surface to protrude from the head to the vicinity of the back of the neck, a whip reduction seat pillow has been proposed (Japanese Patent Laid-Open No. 10-258667).
[0005]
The seat pillow has been proposed as being equipped mainly on the front side of the headrest with a pillow portion in which a cushioning material rich in elasticity and absorbing shock is loaded in a cloth bag. This can be used for a seated occupant to put his head on for a while, but it has been proposed to be attached to the headrest with a string or a band that is longer than the headrest to reduce the whip width. Not preferable.
[0006]
Also, the main body is formed of a foamed foam body provided with an inverted U-shaped recess that fits over the entire top of the headrest, and a bellows provided with a small hole for air venting and a contact plate for head rest An impact-absorbing pillow configured by being housed inside the concave portion of the portion has also been proposed (Japanese Patent Laid-Open No. 11-262425).
[0007]
The shock-absorbing pillow can also be used as a seated occupant for a while. However, the foam foam body must be made thicker so that it has the overall holdability to be applied to the whole from the top of the headrest, so it will be much larger than the headrest and the rear part for the front seat It is not preferable in terms of appearance because it obstructs the occupant's field of view and is large. Moreover, since a recessed part must be formed according to the shape of the headrest, it lacks versatility.
[0008]
In addition, a front-end mechanism assembled from each member such as link bar, cam plate, engagement pin, etc. is installed inside the headrest on the upper end side of the headrest stay shaft, and this front-end mechanism allows the entire headrest to stand in a normal position. A headrest that can be moved forward is also proposed (Japanese Patent Laid-Open No. 11-348630).
[0009]
Even the headrest can be used as a seated occupant who puts his head on for a while if the whole is put forward. However, since it is necessary to provide a complicated mechanism, it becomes expensive, and the direction must be changed whenever necessary, so that it is difficult to cope with an inconvenient use during traveling.
[0010]
