Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea was designed to reduce leg fatigue when sitting on the seat. Regarding the grest storage mechanism.

0002

[Conventional technology]

Recently, various proposals have been made to improve the comfort inside the car interior. being done.

0003 For example, for car seats, move the seat back of the front seat backwards. It can be tilted flat with the seat cushion of the rear seat and used as a temporary bed. Seat structures that allow for a comfortable night's sleep are known.

0004

[Problem that the idea aims to solve]

By the way, when considering the posture of the occupant while driving, the upper body of the occupant is When seated, the seatback can be tilted using a reclining device to make it more comfortable. However, the lower body, especially the legs, can be placed in the passenger compartment with the legs bent. It is necessary to keep the feet on the floor, and this condition impairs the smooth blood flow of the feet and causes the feet to The problem with this is that it is extremely tiring, especially when driving for long periods of time. It was.

[0005] Of course, you can use the above-mentioned seat structure to flatten the seat and stretch your legs. This can reduce foot fatigue, but the work of flattening the legs is complicated, and it is difficult to do so while the vehicle is running. It is difficult to simply stretch your legs.

[0006] On the other hand, one way to solve the above problem is to place the occupant's feet on the front side of the seat cushion. It is conceivable to provide a leg rest that can be moved in and out, but in this case, How to build this considering the tight space around the seat cushion is important.

[0007] With this in mind, this idea has been designed to reduce foot fatigue with simple operations. An object of the present invention is to provide a leg rest storage mechanism.

[0008]

[Means to solve the problem]

Therefore, the leg rest storage mechanism according to the present invention has a front edge of the seat cushion. A support that supports the leg rest body by pivoting the rear end of the leg rest body and supporting the legs of the passenger. In addition to being rotatable between the holding position and the storage position below the seat cushion, A leaf spring is interposed between the two to bias the leg rest body to the supporting position or the storage position. , the support legs are rotatably attached to the front end of the leg rest body, and the leg rest body At the supporting position, the support leg is raised approximately perpendicular to the leg rest body using the stopper. In addition to being positioned in an upright position, the locking member locks the vehicle floor, and the locking portion The leg rest body can be rotated to the storage position when the latch is released. The main points are as follows.

[0009] Here, the leg rest main body may be in a substantially horizontal state in the supporting position, or The front end may be lowered and inclined. Also, how to store the leg rest itself. may be pushed into the bottom of the seat cushion, but in order to simplify the mechanism, It is preferable to let it hang down substantially vertically from the front end of the seat cushion. Also, the leaf spring One or more pieces between the rear edge of the leg rest body and the front edge of the seat cushion, For example, one on each side may be provided.

0010 In addition, when using the leaf spring to bias the leg rest body to the storage position, it is necessary to There is no problem because the leg rest body is held by the supporting legs, but the leg rest When biasing the leg rest body to the supporting position, the leg rest body must always be in a supported state. Therefore, it is necessary to provide a mechanism to lock it in the storage position.

[0011] Also, there is no particular mention of the state of the supporting legs when the leg rest is stored. For example, the supporting legs may be placed on the cabin floor in a state other than the upright state. In terms of space, a locking member is provided on the bottom of the leg rest to hold it along the bottom. It is preferable to do so.

0012

[Effect]

If the occupant wants to rest his or her feet, lift the legrest body forward and also move the support legs. Rotate it forward, position it with the stopper, and raise it roughly against the leg rest body. When the support leg is fixed to the cabin floor by the locking member, the lever is The body of the crest is held in a supporting position by the supporting legs, which allows the legrest to The main body is continuous to the front of the seat cushion, and the occupant's legs are supported by the leg rest main body. You can relax and relax.

[0013] On the other hand, when storing the leg rest main body, release the engagement between the support legs and the locking members. , when the leg rest body is rotated backwards, the leg rest body becomes a seat cushion. It is stored at the bottom of the main body.

[0014] At that time, by using the biasing force of the leaf spring, the leg rest body will automatically move to the storage position. Or it will rotate to a supporting position.

[0015]

The leg rest main body 50 is constructed by internally incorporating a leg rest member and a frame, and the bottom surface of the leg rest body 50 has a mounting plate. A mounting frame 51 is attached, and the mounting frame 51 has a substantially U-shaped frame body 5. A reinforcing pipe 53 is connected to the central part of the mounting frame 51, and both rear ends of the mounting frame 51 A mounting bracket 54 is fixed to the mounting bracket 54 by welding or the like.

[0017] This mounting bracket 54 is formed in a U-shape. A rotating bracket 55 is arranged between both walls, and the pin holes of both brackets 54 and 55 A pivot pin 56 is inserted into the pivot pin 56, and an E-ring is fitted to the tip of the pivot pin 56 to prevent it from coming off. As a result, the rotation bracket 55 is rotatably supported on the mounting bracket 54. It is. Note that the pivot pin 56 may be a split pin.

[0018] An arcuate bent portion 57 is formed on the upper side of the rotating bracket 56. A frame 58 is fixed to 7 by welding or the like, and both ends of the frame 58 are provided with mounting brackets. The mounting bracket 59 is fixed to the racket 59, and the mounting bracket 59 is attached to the seat cushion 2, e.g. It is fixed to the internal frame of the seat cushion 2, and in this way the seat cushion The rear edge of the leg rest main body 50 is located at the front edge of version 2. The supporting position of the rest body 50 (see B in Figure 2) and the storage position below the seat cushion 2 (see A in FIG. 1).

[0019] Further, a locking hole 510 is formed in the rotation bracket 56, and the locking hole 510 has a locking hole 510 formed therein. One end of the leaf spring 511 is inserted and locked, and is also inserted under the front end of both walls of the mounting bracket 54. A locking groove 512 is formed in the portion, and a support pin 513 is inserted into the locking groove 512. , the other end of the leaf spring 511 is engaged with the support pin 513. There is a leg between the front edge of the seat cushion 2 and the rear end of the leg rest body 50. A leaf spring 511 that biases the crest main body 50 to the storage position A is interposed.

[0020] Additionally, a pair of cylindrical brackets 513 are rotatable at the front end of the mounting frame 52. Both ends of U-shaped support legs 514 are fixed to both cylindrical brackets 513. In this way, the support legs 514 are rotatable at the front end of the leg rest main body 50. installed in the function.

[0021] Further, the cylindrical bracket 513 has a guide groove 515 of a predetermined length in the circumferential direction. A stopper pin 516 is fixed to the front end of the mounting frame 52. , the stopper pin 516 is slidably fitted into the guide groove 515. , this causes the support leg 514 to stop at the support position of the leg rest main body 50. It is positioned in an upright position substantially perpendicular to the leg rest main body 50 by the hinge 516. It is now possible to

[0022] In addition, a locking member 517 made of synthetic resin is attached to the passenger compartment floor F using bolts, nuts, etc. The locking member 517 has a receiving portion 51 with which the front end of the support leg 514 can engage. 8 is formed, and thus the support leg 514 is secured to the passenger compartment floor by the locking member 517. When the leg rest body is locked in A F and the locking member 514 is released, 50 is rotated to storage position A by the biasing force of leaf spring 511. . Further, a locking member 519 is fixed to approximately the center of the bottom surface of the seat cushion 2, The front end of the support leg 514 is placed along the bottom surface of the seat cushion 2 on the locking member 519. It is designed to be locked.

[0023] Next, the effects will be explained.

[0024] During normal use of the seat 1, as shown in FIG. rotates downward around the pivot pin 56 at the rear end, and rotates below the front edge of the seat cushion 2. The storage state A is approximately perpendicular to . In this situation, the passenger is seated in seat 1. However, when you bend your legs and place them on the passenger compartment floor F, the leg rest body 50 does not get in the way. It never happens.

[0025] When the occupant stretches his or her legs in such a state A, first place his/her hand on the leg rest main body 50. After lifting it forward and upward against the spring force of the leaf spring 511, the support leg 514 and the locking member 519, and the support leg 514 is attached to the seat cushion 2.

Then, the support leg 514 rotates forward and downward under its own weight and It is in an upright state with respect to the crest main body 50, and the lower end of the support leg 514 is connected to the locking part When engaged with the receiving portion 518 of the material 517, the leg rest main body 50 is supported as shown in FIG. The state B is maintained, and the legs of the passenger are lifted by the leg rest main body 50. , passengers can stretch their legs comfortably and comfortably. As a result, while the vehicle is running, It can greatly reduce the fatigue of the passengers' legs while driving for long periods of time, and it is easy to operate. The leg rest main body 50 can be put into use.

[0026] At that time, operate the reclining device 4 to tilt the seat back 3 backward. This allows the occupant to stretch their legs and back muscles, which in turn allows the occupant to stretch their entire body, including their legs and back muscles. Not only can fatigue be reduced, but it is also possible to take a nap easily.

[0027] On the other hand, when storing the leg rest main body 50, the supporting legs 514 are moved slightly backward. After pushing in and releasing the engagement between the support leg 514 and the receiving part 518 of the locking member 517, The support legs 514 are engaged with the locking members 519 on the bottom of the leg rest main body 50, and the legs When you release your hand from the rest body 50 or lower your hand, the leg rest body 50 will automatically move. Due to the weight and the biasing force of the leaf spring 511, the seat cushion 2 rotates backward and downward. It is stored in the almost vertical position A below the front edge, and in this way the leg rest book can be easily operated. 50 bodies can be stored.
