Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a vehicle seat that is movably disposed within a vehicle interior.

"Prior Art" Conventionally, as this type of vehicle seat, there is one shown in FIG. 4, for example.

That is, a seat body 3 is disposed on a vehicle floor 1 via a seat slide device 2 so as to be adjustable in its longitudinal position.

``Problem to be solved by the invention'' However, in such conventional vehicle seats, the movement of the seat body 3 is limited within the range of the longitudinal position adjustment of the seat slide device 2, and the seat body 3 cannot be moved freely. There was a problem with not being able to move.

The present invention has been developed by focusing on these conventional problems, and provides a vehicle seat in which the seat body can be moved freely within the vehicle interior and can be restrained in the moved position with a simple operation. The purpose is to

``Means for Solving the Problems'' The gist of the present invention to achieve this purpose is to provide a vehicle seat that is movably arranged in a vehicle interior, with vertical members attached to both sides of the seat body. Further, the vertical member is provided with an expansion/contraction mechanism that can increase or decrease the length of the vertical member so that the vertical member is stretched between the floor and the roof and restrains the seat body so that it cannot move. Exists in vehicle seats.

"Operation" When the vertical member is stretched between the floor and the roof, the vertical member is immovably supported by the floor and the roof. The seat body is also immovably restrained by the vertical member.

When the length of the vertical member is reduced by operating the telescoping mechanism to move the seat body to the desired position in the vehicle interior, a gap will be created between the vertical member and the floor or between the vertical member and the roof. This allows vertical members to move without being restricted by the floor and roof.

When the vertical member is moved to the desired position and the length of the vertical member is increased by operating the telescoping mechanism, the vertical member is again stretched and restrained between the floor and the roof, and through the vertical member, The seat body can be restrained at a desired position.

“Embodiment” An embodiment of the present invention will be described below based on the drawings.

1 to 3 show an embodiment of the present invention.

As shown in FIGS. 1 and 2, the vehicle interior 10
A vehicle seat 20 is movably arranged. The vehicle seat 20 is constructed by mounting vertical members 30, 30 on both sides of a seat body 22.

The seat body 22 includes a seat cushion 24 and a seat back 26 which are pivotally attached to a seat cushion 24 so as to be adjustable in angle.

Vertical members 30, 30 are disposed on both sides 25 of the seat cushion 24, the vertical member 30 is divided into upper and lower parts, and an upper column member 31 and a lower bifurcated leg member 35 are connected by a telescopic mechanism 40. It consists of

Pipe members 3 are attached to both bifurcated leg members 35, 35.
6 and 36 are installed, and the seat cushion 24 is mounted and fixed on the pipe member 36.

As shown in FIG. 3, the column member 31 is made of a pipe whose upper end is formed into a disc-shaped backing plate 32, whose lower end is enlarged in diameter, and a female threaded portion 33 is formed on the inner wall of the pipe.

The bifurcated leg member 35 is provided with a stepped portion 37 at the upper end of the pipe material, and a threaded portion 38 is carved in the outer wall of the pipe above the stepped portion 37. A disk-shaped seat plate 39 is formed at the lower end of the bifurcated leg member 35.

The telescopic mechanism 40 is formed by screwing together the female threaded portion 33 of the column member 31 and the male threaded portion 38 of the bifurcated leg member 35.
By rotating the external threaded portion 38 in one direction, the length of the vertical member 30 increases, and by rotating it in the other direction, the length of the vertical member 30 decreases.

As shown in FIG. 2, the floor 12 of the vehicle interior 10
A vertical member 30 is stretched between the roof 14 and the seat body 22 so as to immovably restrain the seat body 22, and the roof 14 has reinforcing members 16, 16, . It has been passed.

The reinforcing member 16 may also serve as a member for reinforcing the roof 14 itself, or may form a backing plate 32 for the column member 31 so that it fits into the reinforcing member 16 and does not move. A fitting portion into which the backing plate 32 fits may be provided in a recessed manner in the reinforcing member 16. Furthermore, the floor 12 side may be reinforced with a reinforcing member.

Next, the effect will be explained.

In FIG. 2, when the vertical member 30 is stretched between the floor 12 and the roof 14, both vertical members 30, 30 are connected to the floor 12 and the roof 14.
4 and is immovably supported. The seat body 22 is also restrained immovably by the vertical member 30.

In order to move the seat body 22 to a desired position in the vehicle interior 10, the expansion and contraction mechanisms 40 of both vertical members 30 are operated respectively, and the female threaded portion 33 of the column member 31 and the male threaded portion 38 of the bifurcated leg member 35 are Rotation in one direction reduces the length of the vertical member 30. Thereby, a gap is created between the vertical member 30 and the floor 12 or between the vertical member 30 and the roof 14, and the vertical member 30 can move without being restrained by the floor 12 and the roof 14.

When the vertical member 30 is moved to a desired position and the respective expansion/contraction mechanisms 40 are operated to rotate the female threaded portion 33 of the column member 31 and the male threaded portion 38 of the bifurcated leg member 35 in the other direction, the respective vertical members 30 length increases. As a result, each vertical member 30 is again restrained in tension between the floor 12 and the roof 14, and the seat body 22 can be restrained in a desired position.

In the embodiment described above, the seat main body 22 and the vertical member 30 are fixed to each other, but the seat main body 22 and the vertical member 30 may be made separable and assembled as appropriate.

The legs are stable, so you can take it out of the car and place it on the ground.

"Effects of the invention" According to the vehicle seat according to the invention, the seat body is immovably restrained by a vertical member that can be stretched between the floor and the roof. The seat body can be installed at the desired position.
