Abstract

PURPOSE: To prevent damage and rickety motion for a long time by providing an elastic member which can come into contact with a striker elastically in a catch condition in a catch mechanism and an intervening member which covers a face in contact with the striker and brings both into contact indirectly. CONSTITUTION: When a seat device is fixed on a floor surface Y, a striker 2 is fitted into a receive groove 35 of a catch mechanism 1 and is brought into contact with a top face 41b of a striker locking groove, and a lock plate 4 is turned from a release position to a catch position and is fixed and held at the catch position by a release plate 5. When the catch mechanism 1 fits into the striker 2, the striker 2 collides against a striker contact face of a holder plate 7 before the striker 2 collides against a bottom 35a of the receive groove 35 due to force of the fitting operation so that the collision of the striker 2 against the groove bottom is avoided in advance. Consequently, the durability of a fixing device Z is increased by the amount of impact which is relaxed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat fixing device for detachably fixing a seat device to a floor surface of a vehicle body.

[0002]

2. Description of the Related Art In some vehicular seats, a seat device attached to the floor surface of a vehicle body can be attached and detached as needed (the entire seat device can be completely attached and detached from the floor surface of the vehicle body). There is a so-called completely detachable type and a so-called flip-up type in which one end side of the seat device is pivotally attached to the floor surface of the vehicle body and only the other end side is detachable.

As a device for fixing the detachable seat device to the floor surface of the vehicle body, for example, as disclosed in Japanese Utility Model Publication No. 4-4906, a striker arranged on the floor surface side of the vehicle body and a striker arranged on the seat device side are provided. There is known a catch mechanism that is arranged and catches the striker to hold the connected state with the striker. Then, in the fixing device having the configuration in which the catch mechanism and the striker are combined, it is possible that the striker collides with the catch mechanism during the catching operation (that is, when the seat is fixed) to generate an impact sound or damage. The striker receiving part of the catch mechanism is used to prevent the catch mechanism and the striker from rattling with each other due to vehicle vibration and the like in the catch state (that is, the seat is fixed) in order to prevent noise. An elastic member such as rubber is placed on the striker to absorb the striker by the elastic member during the catching operation, and in the catching state, the elastic member is always elastically abutted against the striker to prevent the striker from rattling. I try to prevent it.

[0004]

However, in the conventional seat fixing device provided with such an elastic member, the striker is a narrow strip-shaped relatively narrow narrow corresponding to the diameter of the elastic member. Since the elastic member abuts locally and always at the same position in the contact range, the elastic member is rapidly settled due to repeated elastic pressure contact. For this reason, there is a problem that impact noise at the time of catching operation and rattling in the catching state start to occur soon after the use is started, and a measure for solving such inconvenience is desired. Therefore, in the present invention, it is possible to suppress the settling of the elastic member provided in the catch mechanism as much as possible, and to maintain the damage preventive action during the catch operation and the rattling preventive action in the catch state for a long period of time. The purpose of the invention is to provide a fixing device for a vehicle seat.

[0005]

According to the present invention, as a specific means for solving such a problem, a striker arranged on one side of the lower surface of the seat device and the floor surface of the vehicle body to which the seat device is attached, and the other In a fixing device for a vehicle seat, which is disposed on a side and catches the striker to maintain a connected state with the striker, an elastic member capable of elastically contacting the striker in the catch state with the catch mechanism. And an intervening member that covers the contact surface side of the elastic member with the striker to indirectly contact the elastic member and the striker.

[0006]

According to the present invention, the following actions and effects can be obtained with such a configuration. That is, since the elastic member provided in the catch mechanism is provided with the intervening member that covers the contact surface side of the elastic member with the striker and indirectly contacts the elastic member with the striker, the striker during the catching operation. The dynamic load (impact load) applied to the intervening member from the interposing member and the static load acting between the striker and the interposing member in the catching state both cover the contact surface side of the elastic member with respect to the elastic member. Is indirectly transmitted in a wider range through the entire area of. Therefore,
For example, as in the case of the above-mentioned publicly known example, as compared with the case where the striker locally contacts the elastic member with a narrow strip-shaped narrow contact area corresponding to the diameter dimension, the supporting load per unit area on the elastic member side Becomes smaller, the load on the elastic member against the load is reduced accordingly, and the settling is suppressed as much as possible. As a result, the shock absorbing effect and the elastic clamping effect of the elastic member are maintained well for a long period of time,
The impact caused by the striker's collision with the catch mechanism during the catch operation (that is, when the seat is fixed) is mitigated to improve its durability, and between the catch mechanism and the striker in the catch state (that is, the seat is fixed). Noise caused by rattling is prevented as much as possible,
It is possible to obtain a vehicle seat fixing device having high reliability in seat fixing and high commercial value.

The fixing device Z includes a catch mechanism 1 which will be described later attached to the lower surface Xa ₁ of the seat cushion Xa and a striker 2 which is fixed to the vehicle body floor surface Y side. The striker 2 is caught by the catch mechanism 1. By doing so, the seat device X is fixed to the floor surface Y side of the vehicle body, and by releasing the catch state of the striker 2 by the catch mechanism 1, the seat device X is released.
Can be detached from the floor surface Y of the vehicle body.

In the catch mechanism 1, a pair of left and right vertical plate portions 32, 32 and a pair of left and right vertical plate portions 32, 32 facing the pair of left and right flange portions 31, 31 at a predetermined interval are formed by bending the plate body into a hat shape. 32 spaces are continuously formed and a space 3 is provided between them.
The catch bracket 3 is provided with a bottom plate portion 33 that forms part 4. The catch bracket 3 is fixed in a state in which the flange portions 31, 31 are in abutment with the lower surface Xa ₁ of the seat device X, and the bottom plate portion 33 is provided in the pair of vertical plate portions 32, 32. A striker receiving groove 35 that opens to the side and cuts upward in a substantially wedge shape is formed. Further, in the void portion 34 of the catch bracket 3, a lock plate 4 and a release plate 5, which will be described later, are mounted on both sides of the striker receiving groove 35 so as to be coaxial with the lock plate 4. A holder rubber 6 and a holder plate 7, which will be described later, are attached.

The lock plate 4 is integrally formed of a thick plate member having a striker locking groove 41 having a groove width with which the striker 2 can be engaged. The lock plate 4 is pivotally supported by a pin 10 in a direction of arrow AB. In addition, the spring 13 constantly urges it to rotate in the direction of arrow A. The lock plate 4 can be selectively set at two positions, a release position shown by a solid line in FIG. 2 and a catch position shown by a chain line (see reference numeral 4 '). And at the release position,
The open end of the striker locking groove 41 faces the striker receiving groove 35 on the side of the catch bracket 3 to allow the striker 2 to enter and leave the striker locking groove 41. In the catch position, the lock plate 4
The open end of the striker locking groove 41 is closed by the catch bracket 3 to prevent the striker 2 that has entered the striker locking groove 41 from coming off.

The release position is maintained by the shoulder portion 4a of the lock plate 4 contacting a base plate portion 6a of a holder rubber 6 which will be described later, and the rotation in the arrow A direction is restricted. On the other hand, the catch position is held in position by the locking portion 4b of the lock plate 4 being locked by the locking portion 51 of the release plate 5, which will be described later, and the rotation in the arrow A direction being restricted.

The release plate 5 is a plate body rotatably supported by a pin 11 in a direction of arrow CD at a position facing the catch bracket 3, and the locking portion is provided at its tip. 51 is formed.
As shown in FIG. 2, the release plate 5 has the locking portion 51 at the locking portion 4b of the lock plate 4 at the lock position where it is rotated in the direction of arrow C by the urging force of the spring 14. Engagement locks the lock plate 4 in the catch position. On the other hand, by pulling the grip belt 9 provided via the pull tab 8,
The release plate 5 is rotated in the direction of the arrow D to be set at the unlock position, and the locked state of the lock plate 4 at the catch position is released.

Since the holder rubber 6 is integrally attached to and detached from the holder plate 7 in an assembled state, both of them will be described here at the same time. The holder rubber 6 corresponds to the elastic member in the claims and, as shown in FIGS. 1 to 3, is a thin plate having a size that can be accommodated in the void portion 34 of the catch bracket 3. And a thick plate-shaped main body portion 6b continuously formed on the lower surface side of the substrate portion 6a, which are integrally formed of a rubber body having appropriate elasticity. . And this holder rubber 6 is
A pin hole 6d into which the pin 10 is inserted is formed at one end of b, and a lower surface 6c of the main body portion 6b is used as a contact surface 6c that indirectly contacts the striker 2 via a holder plate 7 described later. .

On the other hand, the holder plate 7 corresponds to the intervening member in the claims, and is formed by bending a synthetic resin material or a steel plate having an appropriate composition into a substantially L shape. One of the two curved surfaces 7
a is formed in such a shape as to cover almost the entire contact surface 6c of the holder rubber 6 and is formed into a striker contact surface 7a.
a. Further, an elongated hole 7c corresponding to the pin hole 6d of the holder rubber 6 is formed on the other bent curved surface 7b. As shown in FIG. 3, in this holder plate 7, the striker contact surface 7a is brought into contact with the contact surface 6c with respect to the holder rubber 6, and the elongated hole 7c is made to correspond to the pin hole 6d. It is assembled in a state.

Further, as shown in FIG. 2, the holder rubber 6 and the holder plate 7 assembled as described above are arranged such that the main body portion 6b of the holder rubber 6 is closely opposed to the side surface of the lock plate 4 and the substrate thereof. Part 6a
The lock plate 4 is housed in the void portion 34 of the catch bracket 3 while covering the upper surface side thereof. Then, the holder rubber 6 housed in the void portion 34.
The holder plate 7 and the lock plate 4 have a pin hole 6d of the holder rubber 6 and an elongated hole 7 of the holder plate 7.
c and the pin receiving hole 22 of the lock plate 4 are positioned coaxially with the pin receiving hole 21 of the catch bracket 3, respectively, the pin 10 having the spring 13 attached to one of the shaft ends thereof is attached to the catch bracket. 3 is inserted from one vertical plate portion 32 side to the other vertical plate portion 32 side and the other shaft end of the pin 10 is caulked to be attached to the catch bracket 3 side via the pin 10. There is.

In the assembled state of the holder rubber 6 and the holder plate 7, the substrate portion 6a of the holder rubber 6 is the flange portion 31 of the catch bracket 3.
The striker contact surface 7a of the holder plate 7 is located at almost the same height as the striker receiving groove 3
It faces the striker receiving groove 35 in a state of protruding downward from the groove bottom 35a of No. 5 by a predetermined dimension. Further, in this case, the distance between the striker contact surface 7a and the lower surface 41a of the striker locking groove 41 of the lock plate 4 set at the catch position is set smaller than the diameter dimension of the striker 2 by a predetermined dimension. ing.

According to the fixing device Z having such a structure, when the seat device X is fixed to the vehicle body floor surface Y from the detached state, the striker 2 provided on the vehicle body floor surface Y side is used. The striker receiving groove 35 of the catch mechanism 1 provided on the side of the seat device X is engaged, and this is brought into contact with the upper surface 41b of the striker locking groove 41 of the lock plate 4 set to the release position, and the lock plate Four
Is directly rotated by the contact force from the release position to the catch position, and the lock plate 4 is fixedly held at the catch position by the release plate 5.

When the catch mechanism 1 is engaged with the striker 2 from above, the striker 2 may collide with the groove bottom 35a of the striker receiving groove 35 due to the momentum of the engaging operation. In such a case, before the collision with the groove bottom 35a, the striker 2 collides with the striker contact surface 7a of the holder plate 7 arranged so as to project downward from the groove bottom 35a, and the collision load Is transmitted from the entire area to the main body portion 6b of the holder rubber 6 through the striker contact surface 7a.
The elastic deformation of the shock absorber absorbs and relaxes the shock as much as possible, and the striker 2 is prevented from colliding with the groove bottom 3a. Therefore, the impact sound generated by the catching operation is less likely to occur, and the durability of the fixing device Z can be improved by the extent that the impact is alleviated.

After the striker 2 is once caught by the catch mechanism 1, the catch mechanism 1
The striker engagement distance on the side, that is, the distance between the striker contact surface 7a of the holder plate 7 and the lower surface 41a of the striker locking groove 41 is set smaller than the diameter dimension of the striker 2 by a predetermined dimension. Rubber 6
The body portion 6b is elastically deformed to an appropriate degree, and the elastic force clamps the striker 2 between the striker contact surface 7a and the lower surface 41a of the striker locking groove 41. Therefore, the rattling of the striker 2 is suppressed as much as possible, and the rattling sound accompanying the vehicle vibration is reliably prevented.

By the way, during the catching operation of the striker 2 by the catch mechanism 1 as described above, the shock absorbing action based on the elastic deformation of the holder rubber 6 prevents the generation of impact noise and the like. Although the rattling of the striker 2 is prevented by the elastic clamping operation based on the elastic deformation of 6, the elastic properties of the holder rubber 6 are all required to function properly. Therefore, when the holder rubber 6 becomes settled during long-term use and the settling degree becomes excessive, the holder rubber 6 does not function sufficiently, and the above-described action and effect cannot be obtained. Such excessive settling of the holder rubber 6 is most remarkable when the striker 2 directly abuts the holder rubber 6 and the abutting portion is local and is always a fixed place, as in the above-mentioned known example. The appearance is as described above.

However, in this embodiment,
As described above, the striker contact surface 7a of the holder plate 7 is arranged on the contact surface 6c of the main body portion 6b of the holder rubber 6, and the striker 2 is received by the striker contact surface 7a. Since the force and the continuous clamping pressure are transmitted from the entire area of the striker contact surface 7a to the main body portion 6b side of the holder rubber 6, for example, the striker 2 is attached to the striker contact surface 7a.
Even if the main body portion 6b always comes into contact with the fixed position, the main body portion 6b does not receive a load locally and supports it in a wider range. Moreover, by supporting the load in a wide range, the supporting load per unit area on the holder rubber 6 side is small, and the load on the holder rubber 6 side is reduced accordingly.

Due to these synergistic effects, the settling of the main body portion 6b of the holder rubber 6 is suppressed as much as possible compared with the conventional structure, and the holder rubber 6 is originally kept for a longer period of time. It will maintain its elasticity and function effectively. As a result, the impact-relieving action and the elastic pressure-holding action utilizing the elasticity of the holder rubber 6 can be favorably maintained for a long period of time.

In this embodiment, the fixing device Z applied to the completely detachable seat device X is shown, but the present invention is not limited to this, and for example, a flip-up seat device X is shown. Of course, it is also applicable.
