Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a seat for a large truck.

[Prior Art] Large trucks for long-distance transportation are generally provided with a bed for taking a nap behind the driver's seat and the passenger seat. The width of this bed is limited by the size of the cab, and the cab's longitudinal dimensions are placed behind and above the engine, which is not convenient for placing a cargo bed, so the engine is relatively small. In this case, the dimensions of the cab become smaller, and the width of the bed becomes correspondingly narrower. Therefore, in such a case, the auxiliary seat should be expanded as disclosed in Japanese Utility Model Publication No. 53-22895, or the auxiliary seat should be folded forward so that this part can be used as a bed. It is preferable.

However, when the seat back of the auxiliary seat is folded forward and used as part of a bed, the following problems arise. That is, if the auxiliary driver suddenly applies the brakes while the driver is napping, there is an inconvenience that the napper may be pushed forward. A similar situation occurs when carrying baggage on a bed.

[Problem to be solved by the invention] Therefore, the purpose of the invention is to solve the above problem by replacing the headrest of the auxiliary seat with the back of the seat bag in order to prevent the napper from slipping off the bed. The purpose is to provide seats for large trucks.

[Means for Solving the Problems] In order to achieve the above object, the configuration of the present invention is that a removable headrest is provided at the upper end of the auxiliary seat, and a hole for inserting the headrest is provided on the back of the seat back of the auxiliary seat. The headrest can be inserted into the headrest insertion hole with the seat back of the auxiliary seat tilted forward.

[Function] By folding the seat back 5 of the auxiliary seat 6 forward, it can be used as a bed, and by attaching the headrest 9 to the insertion hole 14 on the back of the seat back 5, a napper is prevented from driving.

[Embodiment of the invention] To explain the invention based on an embodiment, as shown in FIG. An auxiliary seat 6 consisting of a seat cushion 4 and a seat bag 5 is provided at the front, and a bed 7 is arranged behind these seats. The rear of the bed 7 is partitioned by a rear wall 12 having a window 10. A head rest 8 is removably attached to the upper end of the seat bag 2, and an insertion hole 13 (a second
A headrest 9 is attached to the headrest 9 shown in FIG.

The present invention is such that the head rest 9 and, if necessary, the head rest 8 are also used as anti-slip members. That is, as shown in FIG. 2, the auxiliary seat 6 is configured to provide a flat surface at approximately the same height as the bed 7 when the seat back 5 is folded forward. Then, the headrest 9 is removed and replaced into an insertion hole 14 provided on the back surface of the seat bag 5.

In this case, by providing individual insertion holes 14 in the back of the seat bag 5, the headrest 8 of the driver's seat 3 can be attached if necessary, thereby making the effect of preventing nappers from slipping more reliable.

The insertion hole 14 is configured as follows. As shown in FIG. 3, a box-shaped guide member 18 is attached inside the seat bag 5, and an insertion hole 14 is provided in one end wall of the guide member 18. A strut 19 extending from the headrest 9 is inserted into the insertion hole 14 and held by engagement with a leaf spring 20.

As shown in FIG. 4, the guide member 18 has a rectangular opening 23 in one side wall, one end of a plate spring 20 is fixed to the side wall using a rivet 22, and the tip is curved to fit into the opening. 23 into the interior of the guide member 18.

On the other hand, the column 19 of the headrest 9 has a recess 2.
1 is provided, and when the support column 19 is inserted into the guide member 18 from the insertion hole 14, the leaf spring 20
is elastically engaged with the recess 21, and the head rest 9
It is configured so that it does not come off.

By configuring the present invention as described above,
Along with the bed 7, the seat back 5 of the auxiliary seat 6 can be widely used as part of the bed, and the headrests 8 and 9 prevent the napper from slipping forward when the truck brakes suddenly. This can help ensure the safety of nappers.

Moreover, headrests 8 and 9 are seatbacks 5
Since it is made of a soft material as well, even if the napper is pushed forward, it can be safely held down and prevented from slipping to the floor. and,
Since the head rest, which is standardly equipped as an anti-slip member, is simply replaced, it is also useful for reducing costs compared to providing a special anti-slip member.

The embodiment shown in FIG. 5 is an embodiment in which the space of the bed 7 is relatively large. In this case, an insertion hole 15 is arranged at the lower end or rear part of the seat bag 5, and a headrest 9 is inserted into the insertion hole 15. It is designed to be inserted and can effectively prevent the napper from slipping forward from the bed 7.

In the case of this large truck, a parcel box 17 is arranged between the driver's seat 3 and the auxiliary seat 6, and when the driver's baggage is to be placed inside the cab, the headrest 9 is replaced with the insertion hole 14. Possibly on the sides of the driver's seat 3 and on the berth 7
can be widely used as a luggage compartment, and the headrest 9 can prevent luggage from sliding forward.

[Effect of the invention] As mentioned above, this invention has a headrest insertion hole on the back of the auxiliary seat, so when the seatback of the auxiliary seat is folded forward and used as a sleeping berth, the headrest can be attached to the back of the seatback to prevent napping. It is possible to prevent the driver from falling, and it is possible to continue operation by changing the driver and to recover from fatigue.
