Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a vehicle seat, and more particularly to a structure of a vehicle seat in which a seat cushion is detachably attached to a vehicle body.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, in a cab-over type vehicle, for example, there is a seat structure in which a seat cushion constituting the seat is detachably fixed to a vehicle body so that maintenance of an engine provided under the seat can be performed.

As shown in FIGS. 6 and 7, such a seat structure has a lower end of a cabin back panel 104 to which a seat back 103 is fixed, with support plates 102 protruding from the left and right rear ends of a seat cushion 101. After the seat cushion 101 is positioned by inserting it into the insertion opening 105 formed in the seat cushion 101, the front end of the seat cushion 101 is fixed to the floor panel 107 by a clamp 106 having a toggle mechanism.

[0004]

[Problems to be solved by the device]

 However, in the seat structure as described above, when the support plate 102 of the seat cushion 101 forming the seat is inserted into the insertion opening 105 at the lower end of the cabin back panel 104 in which the seat back 103 is fixed. However, since the insertion opening 105 is blocked by the lower end of the seat back 103 and becomes difficult to see, the workability is poor.

Further, in order to improve the workability, it is conceivable to provide a gap between the seat cushion 101 and the seat back 103. However, if such a gap is provided, the seat back 103 passes through the gap. The cabin back panel 104 existing behind the lower part of the vehicle can be seen from the outside and the appearance is impaired.

The present invention has been made in view of the problems of the above-described conventional technology.

[0007]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a vehicle seat in which a seat cushion is detachably attached to a vehicle body below a seat back, and a lower end of the seat back is below the seat back. A space is provided between the seat cushion and the rear end of the seat cushion so that the insertion opening is fully exposed, and a projecting portion that covers the space between the seat cushion and the lower end of the seat back is provided across the entire width behind the seat cushion. The structure is formed as follows.

[0008]

[Action]

 According to the structure of the vehicle seat according to the present invention, since the lower end of the seat back constituting the seat is located above the seat back so that the insertion opening existing below the seat back is fully exposed, When the protrusion provided at the rear end of the seat cushion is inserted into the mouth, the alignment is facilitated and the workability is improved.

Further, according to the present invention, since the protruding portion for covering the gap with the lower end of the seat back is formed over the entire width behind the seat cushion, the gap between the seat cushion and the seat back is formed by the protruding portion. It is blocked by and becomes good in appearance.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Here, FIG. 1 is a perspective view showing the whole of a detachable seat adopting a seat structure according to the present invention, FIG. 2 is a perspective view of a seat cushion, and FIG. 3 is taken along line AA of FIG. It is sectional drawing of a part. FIG. 4 is a side view of a detachable seat adopting the seat structure according to the present invention, and FIG. 5 is an enlarged sectional view of a portion B of FIG.

In FIG. 1, reference numeral 1 denotes an entire seat, and the seat 1 is mainly composed of a seat cushion 2, a seat back 3, and a headrest 4 as shown in FIG. 1, and the seatback 3 and the headrest 4 are provided. Is fixed to the cabin back panel 5 via a mounting bracket (not shown).

As shown in FIGS. 2 and 3, the seat cushion 2 includes support plates 7, 7 welded and fixed to the left and right rear ends of a seat cushion panel 6, which is a skeleton of the seat cushion 2, and the seat. The cushion plate 6 has a hook 8 welded and fixed to the center front end thereof, and the support plates 7 and 7 are provided on a lower member 9 welded and fixed to the lower end of the cabin back panel 5 as shown in FIG. The hook 8 at the front end is inserted into the insertion holes 10 1, 10 and fixed by a clamp 12 having a toggle mechanism provided on the floor panel 11 so that the hook 8 is detachably attached to the vehicle body.

As shown in FIG. 5, the lower end of the seat back 3 fixed to the cabin back panel 5 has sufficient insertion openings 10, 10 into which the support plates 7, 7 of the seat cushion 2 are inserted. As can be seen from the outside, a gap X is provided between the seat cushion 2 and the rear end of the seat cushion 2, which is detachably attached to the vehicle body.

Further, on the rear upper surface of the seat cushion 2, as shown in FIG. 2 or 3, it is formed of the same material as the skin 14 which covers the pad 13 placed on the seat cushion panel 6 from above. The projecting portion 15 and the extended portion 16 are sewn integrally with the outer skin 14 in the upward direction over the entire width of the seat cushion 2, and the extended portion 16 is tilted rearward and the tip thereof is A bog ring 18 through which a trim wire 17 having a crawling inner side is passed through is mounted to adjust the shape of the skin 14 of the seat cushion 2.

When the seat cushion 2 configured as described above is mounted on the vehicle body, the support plates 7, 7 provided at the rear end of the seat cushion 2 are first inserted into the seat back 3 under the seat back 3. Insert into mouth 10,10. At this time, since the lower end of the seat back 3 is provided with a gap X between the seat cushion 2 and the rear end of the seat cushion 2 so that the insertion openings 10 and 10 can be sufficiently confirmed from the outside, the support is provided. The positions of the tips of the heating plates 7 and 7 and the insertion openings 10 and 10 are easily aligned, and the insertion is smoothly performed.

When the support plates 7 and 7 of the seat cushion 2 are completely inserted into the insertion ports 10 and 10 and positioned, as shown in FIG. 5, the rear upper surface of the seat cushion 2 is shown. The protruding portion 15 provided on the seat abuts on the lower end of the seat back 3 and closes the gap X between the seat cushion 2 and the seat back 3, so that the insertion openings 10, 10 cannot be seen from the outside.

After that, the hook 8 provided at the front end of the seat cushion 2 is fixed by the clamp 12 having the toggle mechanism provided on the floor panel 11, so that the seat cushion 2 is attached to the vehicle body. The seat cushion 2 is detached and attached in the reverse order of the above.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications and changes can be made based on the technical idea of the present invention. It is natural to meet.
