Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a removable fixing device for a vehicle seat, and in particular, the present invention includes a fixed pawl and a movable pawl that engage a striker fixed to the floor of a vehicle. This invention relates to a seat that can be attached or detached by rotating a movable claw with an operating lever.

BACKGROUND TECHNOLOGY Vehicle seats are generally fixed to the floor of the vehicle, but in the case of so-called one-box type vehicles,
The seats are removably fixed so that the cabin can be used for both cargo and passengers. One example of this kind of removable fixing device for a vehicle seat is the one shown in FIGS. 3 and 4. The fixing device is one that is installed at the seat cushion or base of the seat, facing oppositely to the lower left and right sides of the back arm of the seat back. A base plate 1, which is one of the fixing devices fixed in a bilaterally symmetrical structure, includes a fixed pawl 3 and a movable pawl 4 for gripping a striker 2 fixed to the floor surface of the vehicle. The movable claw 4 is rotatable about a shaft 5, and the shaft 5 is supported and fixed to the base plate 1 and the sub-plate 6 with the movable claw 4 loosely fitted therein. The movable claw 4 is integrally formed with an operating lever mounting portion 7, and a coil spring 9 is disposed between the operating lever mounting portion 7 and a locking portion 8 protruding from the base plate 1. 4 is given a clockwise rotational force. On the other hand, a housing 10 is attached to the outside of the sub-plate 6 by caulking the shaft 5, and a damper 11 made of rubber or the like that presses against the striker 2 is accommodated and fixed within the housing 10. In addition, 12 is a latch part forming a part of the reclining mechanism, and a back arm equipped with a reclining mechanism that engages with this latch part is connected so as to be rotatable about the shaft 12a, but in the present invention, the reclining mechanism is essential. Since this is not a constituent matter, its explanation will be omitted.

Therefore, when fixing the seat to the floor of the vehicle,
When the striker 2 is pressed between the fixed claw 3 and the movable claw 4 and the seat is pressed downward, the movable claw 4 rotates counterclockwise against the force of the coil spring 9, and the fixed claw 3 The space between the movable claws 4 is opened, and the striker 2 enters between the two claws, and then the movable claw 4 is closed by the force of the coil spring 9, and the striker 2 is pressed against the fixed claw 3. On the other hand, when the striker 2 enters between both claws, the striker 2 comes into pressure contact with the lower end of the damper 11. The seat is fixed to the floor in this way, but if you need to remove it again, manually tilt the operating lever attachment part 7 of the movable claw 4 counterclockwise to widen the gap between the two claws. Since the damper 11 is compressed, its restoring force lifts the shaft 5 upwards, which causes the striker 2 to separate from both claws and the seat to be lifted off the floor and separated.

Problems to be solved by the invention However, according to the above-mentioned conventional vehicle seat removable fixing device, when removing the seat from the floor,
The movable claws 4 that engage the striker 2 must be rotated in the same direction at the same time via the operating levers at least at the operating lever mounting portions 7 of the base plate 1, which are mounted symmetrically at the bottom of both left and right sides of the seat back of the seat. cannot rotate left and right at the same time,
Removing the seat is extremely troublesome. Of course, even if you operate the left and right operation lever mounting parts 7 separately,
The seat is lifted off the floor by the elasticity of the damper 11, but it may stay only on one side. especially,
Regardless of whether the seat is for personal use and has a narrow seat back, if the seat back is wide, such as a bench seat, one person must use both hands to operate the operating lever mounting portions 7 on the left and right sides of the seat. It is impossible to do so. Therefore, there was a problem in that when a horizontally long seat such as a bench seat had to be removed from the floor of the vehicle, at least two people had to do the work. In addition, when the seat is fixed, the damper 11 that the striker 2 comes into pressure contact with is
Since it is essential that the seat be held without looseness and with some elasticity without impairing its supporting function, a housing 10 is provided to prevent and protect the damper 11 from deformation. ,
Since a load is directly applied to the housing 10, it is easily deformed or damaged, and the intended function of the damper 11 may be impaired.

Means for Solving the Problems In order to solve the above problems, the present invention includes a base plate fixed to the side of a vehicle seat, a fixed claw provided on the base plate, and a striker that engages the striker in opposition to the fixed claw. A movable pawl rotatably supported on a base plate to hold the movable pawl, an operating lever connected to the movable pawl, a cylindrical body into which one end of a shaft interlocked with the movable pawl is loosely fitted, and a cylinder formed at the other end of the shaft. a joint portion that connects a connecting rod that is interlocked with a fixing device provided on the opposite side; a sub-plate and a housing that are integrally connected via the cylinder; and a sub-plate that is fixed to a base plate. In addition, a removable fixing device for a vehicle seat is provided, characterized in that a housing houses a damper to which the striker presses.

Effects According to the above structure of the present invention, not only the operating lever and the movable pawl, but also the shaft thereof can rotate as one unit, and the shaft is loosely fitted into the cylinder without directly contacting the damper. Since the damper does not impede rotation. Therefore,
The shafts of the movable claws in the pair of upper fixing devices located at the lower left and right sides of the seat can be interlocked with each other by a connecting rod. Thus, even in the case of a seat such as a bench seat, when removing it from the floor, by operating either the left or right operation lever, both the left and right movable claws can be opened in conjunction with each other at the same time, making removal simple and easy. It is possible. In addition, since both ends of the cylinder are connected to the sub-plate and the housing, the housing is integrated with the sub-plate and has the rigidity to prevent deformation due to compression of the damper, preventing the occurrence of so-called play. , improves the regulation and protection functions of the damper and improves its durability.

Embodiment The present invention will be described below based on an illustrated embodiment. FIG. 1 is a front view and a partially sectional side view corresponding to FIG. 3 and FIG. 2 to FIG. 4, respectively. In the drawings, the same reference numerals indicate the same or corresponding parts as in the conventional example, so the explanation thereof will be omitted.

The movable claw 4 is operatively connected to the shaft 5, while
One end of the shaft 5 is rotatably loosely fitted into a cylindrical body 13 that contacts the damper 11, and the other end is formed with a joint portion 14 having an irregular cross section. Therefore,
Even if the cylinder 13 is fixed by contacting the damper 11, the shaft 5 can rotate within the cylinder 13.
The movable claw 4 and the shaft 5 may be connected by any means, such as welding, integral molding, or spline engagement, but in this example, the shaft 5 is formed with an enlarged portion 15 of irregular cross section, The movable claw 4 is provided with a shaft hole 16 into which the enlarged portion 15 is tightly fitted, and the two are engaged with each other. Both ends of the cylindrical body 13 are supported and fixed to the housing 10 that accommodates the damper 11 and the sub-plate 6, respectively. And the lever mounting part 7
A lever 7a is attached and fixed to the lever 7a by pins 7b and 7c, and when the lever 7a is turned counterclockwise, the movable pawl 4 and the shaft 5 are not affected by the damper 11 and rotate as one unit.

On the other hand, a connecting rod 17 having a predetermined length and extending in the axial direction is removably connected to the joint portion 14, with its irregular cross section tightly fitted. This connecting rod 17 operatively connects the shafts 5 of the pair of fixing devices fixed to the lower portions of the left and right sides of the seat. Therefore, when the seat back is horizontally long, such as a bench seat, by providing the connecting rod 17, when the operating lever 7a of either the left or right fixing device is operated, both the left and right movable claws 4 can be rotated at the same time. and interlock.

The present invention is as described above, but when a reclining mechanism is installed, if the operating lever 7a is interlocked with the back arm, the operating lever 7a will interlock with the movable claw 4 when the seat back is reclined at a certain angle. opens and the damper 11 disengages the striker 2, so that the seat can be removed from the floor at the same time as the seat bag is lowered.

Effects of the invention According to the invention described above, both ends of the cylindrical body into which the shaft of the movable claw rotatably fits loosely are connected to the sub-plate and the housing, respectively, so the housing is integrated with the sub-plate, It is possible to maintain rigidity that prevents deformation due to compression of the damper, and also prevents rattling, thereby improving the regulation and protection functions of the damper and improving its durability. Further, by connecting a connecting rod to the joint portion, the pair of left and right fixing devices can be configured to be interlocked. In this case, when one of the operating levers is operated, the other operating lever and movable pawl are linked, so even in the case of a bench seat, one person can perform the removal work.
Moreover, since the structure is configured to be interlockable, one of the operation levers of the fixing device attached to the seat as a pair on the left and right sides can be omitted, and other effects are achieved.
