Description

[Detailed explanation of the invention] There are various configurations of footrests installed in vehicles (see, for example, Japanese Utility Model Application Publication No. 158335/1983), but this invention was developed to provide footrests for passengers in the rear seats of vehicles such as buses. The present invention relates to the configuration of a footrest for a seat provided for the purpose of the present invention.

First, the structure of a conventional footrest will be explained. As shown in FIG. 1, a footrest 2 is provided at the rear lower part of a seat 1.
There are some that are fixed to the seat 1, and others that are designed to be rotated in the E direction and stored. In addition, as shown in Fig. 2, there is a seat at the bottom of the rear of the seat 3 so that it can be used according to the occupant's body position.
There are two levels of footrests 4 and 5 on the top and bottom,
Some are fixed to the seat 3, while others are rotatable in the F and G directions for storage.

In these structures, if there is only one footrest as shown in FIG. 1, it may not be suitable for the body position of the occupant. Furthermore, when a two-tiered footrest is used as shown in FIG. 2, the footrests of approximately the same size are mounted on the upper and lower sides, so there is a drawback that the footrest cannot be made large due to the installation space. And since only one of the top and bottom is used, it is a shame that the other is wasted.

The present invention was devised to eliminate such drawbacks, and the footrest can be formed at an upper (higher) or lower (lower) position as required.
It is also configured so that it can be stored when it is not needed.

Next, the structure of the present invention will be explained with reference to embodiments shown in FIG. 3 and the following drawings.

Seat 10 has cushion 11 and backrest 1
2, and a rear frame 13 is embedded in the rear lower part of the cushion 11 in the vehicle width direction. And brackets 14, 14 are attached to both ends of the rear frame 13.
is permanently installed.

Bearing portion 14a of both brackets 14, 14,
A rotary shaft 16 to which support arms 15, 15 are fixed is freely rotatably spanned between 14a. And the mounting holes 15a at the tips of the support arms 15, 15,
Pins 18, 18, which are implanted on both sides of the footrest main body 17, are fitted into the pins 15a so as to be freely rotatable.

Furthermore, a locking arm 19 for the pin 18 of the footrest body 17 is attached. That is, the pin 18 is rotatably fitted into the mounting hole 19c of the locking arm 19. And at the tip of the latching arm 19,
A recessed engaging portion 19a is provided. On the other hand, an engagement pin 21 is fixed to the fixing member 20 of the cushion 11 so as to be positioned above the bearing portion 14a of the bracket 14. The engaging portion 19a of the locking arm 19 is formed so that the engaging pin 21 can be locked therein.

Further, a compression coil spring 24 is stretched between a pin 22 implanted in the bracket 14 and a pin 23 implanted in the support arm 15.

Because of this structure, this footrest can be rearranged in three ways as described below.

FIG. 3 shows the footrest located at the lower part. That is, if the support arm 15 is rotated downward around the bearing part 14a as shown in the figure, the coil spring 24 stretched between the pins 22 and 23 will be located below the bearing part 14a. Therefore, the compressive force of the spring 24 urges the support arm 15 to rotate in the H direction, and the edge of the support arm 15 comes into contact with the stopper portion 14b of the bracket 14. In other words, a stable triangle is formed with the bearing portion 14a as the apex and the line connecting the pins 22 and 23 as the base, and the edge of the support arm 15 and the bracket 1
The support arm 15 is fixed in a state in which it is in contact with the stopper portion 14b of No. 4. Then, the stopper part 19b provided at the edge of the latch arm 19 is connected to the support arm 1.
5 and the footrest main body 17 can be placed in the lower part and used.

FIG. 4 shows the footrest in a higher position. That is, the support arm 15 is rotated upward around the bearing portion 14a as shown in the figure, and the locking arm 19 is further rotated to lock the engagement portion 19a to the engagement pin 21. In this way, pin 2
Coil spring 2 stretched between 2 and pin 23
4 is positioned above the bearing portion 14a, the compressive force of the spring 24 urges the support arm 15 to rotate in the J direction. In other words, the line connecting pins 22 and 23 is the upper side,
A stable triangle is formed with the bearing portion 14a as the apex located below. The support arm 15, the locking arm 19, the bearing portion 14a and the engagement pin 21
Since a stable triangle is formed by the line connecting the two, the support arm 15 can be fixed at this position and the footrest main body 17 can be used at a high position.

In FIG. 5, the footrest is stored in the back of the cushion 11. That is, the stopper portion 19b of the latch arm 19 is connected to the support arm 15.
The support arm 15 is rotated around the stopper portion 14a to abut the engagement pin 21, and is stored in the back of the cushion 11 as shown in the figure. At this time, since the coil spring 24 stretched between the pins 22 and 23 is located above the bearing portion 14a, the compressive force of the spring 24 causes the support arm 15 to rotate in the J direction. Forced.
In other words, a stable triangle is formed with the line connecting the pins 22 and 23 as the upper side and the bearing portion 14a as the lower apex, and the support arm 15
Adjust the position of.

In this state, the support arm 15 is stationary and the footrest is retracted.

The present invention is constructed as described above, and the footrest can be selected to be used in a lower or higher position as required, and can be retracted when not needed. It has a simple structure with no waste, can be rearranged in three ways, and has the advantage of being able to effectively utilize the limited space inside the vehicle without taking up much space.
