Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a vehicle seat, and more particularly to an improvement in the seat cushion structure of a vehicle seat including a seat longitudinal slide mechanism and a lifter mechanism.

[Conventional technology]

In general, a vehicle seat includes a seat cushion and a seat back that is erected behind the seat cushion and can be rotated freely by a reclining mechanism, and the entire seat is supported on the floor of the vehicle body by a front-back sliding mechanism, etc. The seat is configured so that it can be slid and adjusted in the longitudinal direction of the vehicle body, so that a seated state can be obtained according to the body shape and preference of the seated person. In addition, in recent vehicle seats of this type, in addition to the above-mentioned slide mechanism, the seat cushion portion is supported by parallel links or the like so as to be movable up and down in the vertical direction of the seat, so that the seat can be brought into the above-mentioned seating state. Various types of seats have been proposed that are equipped with a lifter mechanism for vertical adjustment that allows for more appropriate adjustment of the height of the seat. In this case, in order to ensure the strength of the seat back against the load from the occupant, the seat back is supported on the front and rear sliding mechanism via a reclining mechanism, and only the seat cushion is supported via a lifter mechanism so that it can be raised and lowered. It is commonly done.

By the way, in this type of vehicle seat, cushion finishers are generally attached to both the left and right sides of the seat cushion so as to cover the above-mentioned front and back slide mechanism, lifter mechanism, reclining mechanism, etc. This method is effective in obtaining a good-looking sheet.

[Problem that the invention attempts to solve]

However, in a vehicle seat that has both the above-mentioned longitudinal slide mechanism and lifter mechanism, when the seat cushion is raised, the above-mentioned seat cushion is required between the upper end of the cushion finisher and the side part of the seat cushion. The above gap occurred,
Not only does it look bad, but there is also the risk that dirt and foreign objects may get into this space, causing problems such as malfunction of the mechanisms mentioned above, so it is necessary to take some countermeasures. There is.

In particular, in this type of vehicle seat, both sides of the seat cushion are configured to bulge toward the seating surface.
By holding the seated person with the required cushioning properties and holding force from both the left and right sides when sitting, the seat can enhance the holding feeling of the seat and improve the feeling of sitting comfort. In this case, the lower sides of both sides of the seat cushion are cut diagonally downward, so that when the seat cushion rises as described above,
The mechanical section under the seat was exposed to the outside between the seat and the finisher, making the above-mentioned problems unavoidable. In order to form the above-mentioned bulge, the side edge of the seat cushion frame rises diagonally upward, and the thin pad ends wrap around along this edge, and the skin material covers the surface. This was because it was attached.

Of course, if the side edges of the seat cushion frame described above are formed by deep drawing to stand up almost vertically, the pad end portions will also extend almost vertically, and even if the seat cushion rises, Although it is possible to create a structure in which there is no gap between the upper end of the finisher and the upper end of the finisher, deep drawing of the frame made of thin plate material
It has been difficult to realize this because there is a risk of cracks occurring during press working.

[Means for solving problems]

The present invention has been developed in view of the above-mentioned problems.The seat cushion is supported by the upper rail of the front-rear slide mechanism so that it can be raised and lowered by parallel links via the lifter mechanism, and both of the above-mentioned mechanisms are installed on both sides of the seat cushion. In a vehicle seat comprising a covering cushion finisher, a side edge of a cushion frame of the seat cushion is formed to be inclined diagonally upward and stand up;
A pad material is placed on the cushion frame, bulges are formed on both sides of the pad material along the slope of the side edges of the cushion frame, and the shoe rises obliquely upward. The cushion pad end portion, which is arranged around the outside of the side edge of the cushion frame, is formed thick so that the outer surface facing the upper end of the cushion finisher extends downwardly. Features.

[Effect]

According to the present invention, the side edges of the cushion frame of the seat cushion can be formed to stand up obliquely upward, and both sides of the pad material can be formed along the inclination of the side edges of the cushion frame. A bulging portion can be formed, and the portions on both sides of the seat cushion facing the upper end of the cushion finisher can be configured as substantially vertical surfaces, so that even when the seat cushion rises, there is no gap between the seat cushion and the finisher. It is possible to eliminate the problem of conventional problems such as unsightly appearance.

〔Example〕

Hereinafter, the present invention will be explained in detail using embodiments shown in the drawings.

1 to 3 show an embodiment of the vehicle seat according to the present invention, and in these figures, the vehicle seat, which is designated as a whole by reference numeral 1, is attached to a vehicle body (not shown), as is clear from FIG. A seat cushion 4 is supported on an upper rail 2a of a front-rear sliding mechanism 2 disposed on the floor in the front-rear direction of the seat via a lifter mechanism 3 with a parallel link so that it can be raised and lowered; A seat back 6 is erected and supported in a tiltable manner via a reclining mechanism 5 with respect to the upper rail 2a.
It is composed of etc. Furthermore, cushion finishers 7 are arranged on both sides of the seat cushion 4 to cover the mechanisms 2, 3, 5, etc., as shown by imaginary lines in FIG. This can be easily understood from FIGS. 1 and 2.

Now, according to the present invention, in the above-mentioned configuration, both sides of the seat cushion 4 are supported on the front and rear slide mechanism 2 by the lifter mechanism 3 so as to be freely raised and lowered, and both sides of the seat cushion 4 are covered with the cushion finisher 7. The cushion pad end portion 11, which is disposed around the outside of the side edge of the cushion frame 10 that stands up with an upward inclination, is attached to the outer surface (indicated by A in the figure) opposite to the upper end portion 7a of the cushion finisher. It is characterized in that it is formed thick so that it hangs down and extends.

Further, the cushion frame 10 of the seat cushion 4 is press-molded from a thin plate material, and the frame side edge 10a of the cushion frame 10 is formed to be inclined diagonally upward.

Here, 12 in FIG. 1 is the cushion frame 1.
This is a bulge portion of the pad material 14 formed along the inclination of the side edge 10a of the frame.

The surface of the pad material 14 is covered with a skin material 13, and the end of the skin material 13 is clipped to the lower end of the frame side edge 10a.

According to such a configuration, the portion of the side portion of the seat cushion 4 facing the upper end portion 7a of the cushion finisher can be configured as a substantially vertical plane A, and even when the seat cushion 4 moves upward, It is possible to avoid gaps between the finisher 7 and the finisher 7, which is unsightly, and also prevents the mechanisms 2, 3, 5, etc. from malfunctioning due to dirt entering the interior. The practical effects of this can be easily understood.
