[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a truck seat that can be used as an auxiliary sleeper.

[Prior Art] In a large truck, when two drivers take turns driving for a long period of time, one of the drivers can take a nap in the bed behind the driver's seat. On regular overnight flights, it is desirable that two people be able to take a nap at the same time to recover from fatigue and to make time. However, the berth only has space for one person, and the space between the driver and passenger seats is blocked by the engine hood, so the seat cannot be used as a berth.

According to the present invention, the backrest 14 of the passenger seat 27 is
A cushion material is housed inside the backrest 14 so that it can be folded forward and used as a bed. The seat part 12 can be removed and replaced onto the storage box 10.

As shown in FIG. 2, the divided seat portion 12 is
A mounting frame 17 consisting of a pair of front and rear pipes extending in the transverse direction fixed to the middle floor plate 2 via a bracket,
Supported by 18. Therefore, the engagement pieces 20 and 21 are supported on the bottom surface of the seat portion 12. The engaging piece 20 is composed of a plate spring having an inverted U-shape in cross section, and is elastically engaged with the mounting frame 17. The engagement piece 21 is a plate piece extending rearward and diagonally downward from the bottom surface of the seat portion 12, and is engaged with the lower side of the mounting frame 18.

As shown in FIG. 3, an engagement piece 22 having an inverted U-shaped cross section and extending in the front-rear direction is provided on the side portion of the bottom surface of the seat portion 12.
is supported. Moreover, when the seat part 12 is removed,
The aforementioned engaging piece 21 is configured to be able to lock a box-shaped elastic cover 21a made of rubber or the like thereto. To surround one side and the rear of the storage box 10,
The mounting frame 30 is made of a tube bent into an L shape.
It is fixed on the engine hood 4 by three struts 33.

Note that the height of the storage box 10 placed on the engine hood 4 is such that when the seat 12 is supported thereon, the height of the storage box 10 is the same as the upper surface of the seat 12 and the backrest 14 of the passenger seat 27.

Therefore, in FIG. 2, when the front end side of the seat portion 12 is pulled up, the engaging piece 20 comes off from the mounting frame 17, and then the engaging piece 21 comes off from the mounting frame 18.

As shown in FIG. 4, the seat portion 12 is rotated half a turn on a horizontal plane, the elastic cover 21a is engaged with the engagement piece 21, and the elastic cover 21a is placed on the storage box 10. The engagement piece 22 is attached to the frame portion 32 in the front and back direction of the mounting frame 30, and the engagement piece 20 is attached to the frame portion 31 in the lateral direction.
are elastically engaged with each other.

When the backrest 14 of the passenger seat 27 is folded forward,
As shown in FIG. 4, the seat portion 12 and the backrest 14 form a flat surface at the same height with almost no gap, and the driver can use it as a bed for napping.
