The present invention mainly relates to a seat belt chuck device used in a vehicle.

Some of the chuck mechanisms thus far have been to push and release the latch member by sliding the push button or by moving the latch member in a horizontal direction perpendicular to the tongue insertion direction.

However, it is not possible to say that the parts of these parts have defects in the number, size and shape of the parts, so that the ease of manufacturing the device, the simplicity of the device, and the loosening between the tongue and the latch member are sufficient in terms of smoothness.

The present invention has been made in this respect. Therefore, the first object of the present invention is to provide a chuck device composed of a relatively small number of small sized parts and at the same time, while making the chuck device easy to manufacture and simple and cost-effective.

The second object of the present invention is to make a chuck device that is easy to assemble in a stacking manner.

The third object of the present invention is to create a chuck device uniquely designed for smooth release of the cam surface of the push button member.

These objects are simple but uniquely shaped clasp members having a base member and a part which is supported to be movable on the base member and which is movable between a first position and a second position having a vertical relationship when viewed from the base member, and a clasp member. A biasing member against the member, a tongue inserted into the base member, and a sliding base that can slide over the base member parallel to the flat base member to move the latch portion of the clasp member between the first position and the second position. And a button member, wherein the push button member and the latch portion are engaged with the latch member to be fixed to the base member when the push button member and the latch portion are at their first position or the second position.

Here will be described embodiments embodying the technical idea of the present invention.

1 is an exploded perspective view of a first embodiment of the present invention.

The chuck device shown here has a clasp member having a base member 1, a slider 10 arranged to slide in the longitudinal direction of the base member, and clasp portions 24a and 24b which are normally pivoted on the base member ( 20) one end is fixed to the base member by a rivet 35 and the other end is push button having a leaf spring 30, cam surface 48a, 48b moving over the upper ends 26a, 26b of the end of the clasp member. The member 40, the notches 84a and 84b which engage the latch portions 24a and 24b of the clasp member, and the tongue 80 having a rectangular hole 82 through which a belt (not shown) passes. The base member 1 is made up of the flat bottom part 2 and the mouth wall parts 2a and 2b on both sides of the bottom part 2.

The flat bottom part 2 forms the H-shaped hole 6 substantially, and has the short protrusion part 7a and the long protrusion part 7b which face each other. The slider 10 with the through hole 14 is fitted into the long projection 7b, and is biased forward by the coil spring 16 (i.e., in the right side in FIG. 1). 7b) is supported by the cut end surface 15 of the slider 10, and the other end is fitted to the projection 7a. The mouth wall portions 2a and 2b of the foundation subsidiary part 1 form holes 4a and 4b facing each other so that the latch member can be held.

Ear portions 22a and 22b formed on both sides of the clasp member 20 are loosely fitted into the holes 4a and 4b so that the clasp member 20 is supported to allow a general pivoting motion. The holes 4a and 4b are shaped so that the clasp member 20 is held obliquely.

The clasp member 20 has a protrusion protruding backward, which is divided into two tails at the end.

Similar bifurcated ends 37a, 37b of the leaf spring member 30 contact the upper ends 26a, 26b of the tail to tilt the clasp member 20 downward with respect to its front ends 21a, 21b. .

Circular holes 32 were formed in the opposite distal end of the leaf spring 30.

The circular hole 32 and the circular hole 34 formed at the end of the member 36 attached to the chuck device at the fixed position and the circular hole 33 formed at the flat bottom name of the base member are mutually provided. Aligned there, the rivets 35 pass through and fasten these members tightly together.

On the leaf spring 30 and the clasp member 20, there is a push button member 40 which can slide the upper surfaces of the input portions 2a and 2b of the base member 1. The push button member 40 has a cam surface that is formed upwardly inside the bifurcated portions 42a and 42b protruding backward, so that the push button member 40 engages the cam surface. The latch member 20 rotates upward against the biasing force of the leaf spring member 30 when sliding backward with the hem of the tail of 20).

The lower part of the bifurcated part 42a, 42b protrudes downward from the bottom surface of the push button member 40, and the push button which slides the upper end surface of the mouth wall part 2a, 2b of the base member 1 The movement of the member 40 is guided and limited within a defined range.

Furthermore, the hole 46 extends forward from the rear end face of the recess of the push button member 40 to receive one end of the coil spring 50. The other end of the coil spring 50 is shown in FIGS. As evident in FIG. 3, the push button member 40 is supported by a rib 77 extending laterally to the inner surface of the top cover member 70 covering the base member 1. Therefore, the push button member 40 is usually moved forward. Here, the coil spring 50 interferes due to the space 31 between the two-branched tail of the clasp member 20 and the two-branched ends 37a and 37b of the leaf spring member 30. Note that you can increase without receiving.

The top cover 70 has a cutout 72 for the push button member 40 at the foremost part, a projection 78a, 78b at the rear part, a screw hole 74a, 74b at the middle part, and a cutout at the front part ( 73a, 73b). These are fitted into and aligned with the thin holes 68a and 68b and the screw holes 64a and 64b of the undercover member 60 and the back portions 61a and 61b, so that the top cover member 70 and the bottom cover member ( Combination of 60) covers the base member (1). The fine holes 63a and 63b of the portion where the screws 66a and 66b are inserted into the aligned screw holes 74a and 64a and 74b and 64b and bent backwards of the undercover member 60 are formed by the mouth of the base member 1. The cutouts 5a and 5b in the wall portion are received so that the insertion opening 62 of the undercover member 60 is aligned with the front hole of the undermember 1.

2 shows how the tongue 80 is inserted into the tongue insertion opening 62 to engage the clasp member 20. At this time, the clasp portions 24a and 24b of the clasp member 20 are in the first position. The position of the front end faces 21a, 21b of the clasp member, which is in contact with the front ends of the holes 4a, 4b of the mouth wall portions 2a, 2b of the base member 1, is the notch 84a, 84b of the tongue 80. It is above the position of the clasp portions 24a and 24b of the clasp member 20 coupled with the.

Therefore, even when the tongue 80 is to be taken out in the state shown in FIG. 2, the engagement of the clasp 20 and the tongue 80 is not loosened because of the front end surface 21a, by the leaf spring member 30. This is because the latch member 20 which is subjected to the counterclockwise torque with respect to 21b) receives more of the lock in the same direction.

When the force is applied to the inclined front surface 44 of the push button member 40 by hand, the push button member 40 slides backward.

As shown in FIG. 3, the protruding portion of the clasp member 20 is lifted by the cam surfaces 48a and 48b and the clasp member 20 is against the biasing force of the leaf spring member 30. It rotates clockwise in FIG. 3 with respect to the front end faces 21a and 21b. Therefore, the clasps 24a and 24b go to the second position. In this position, the clasps 24a and 24b are driven over the upper surface of the tongue 80 to disengage the engagement between the clasps 24a and 24b and the cutouts 84a and 84b of the tongue and at the same time the slider 10 The tongue spring 80 is pushed forward by the coil spring 16 that has accumulated the restoring force.

In addition, it should be noted that the latch portions 24a and 24b remain in their second positions because the slider 10 remains in the forwardly slipped position until the tongue 80 is inserted.

Therefore, when the tongue 80 is inserted, the tongue 80 does not need to lift the latch portions 24a and 24b of the latch member 20 to prevent erroneous bites.

Rather, the block walls 3a and 3b are provided in the mouth walls 2a and 2b to prevent the tongue 80 from floating on the flat bottom 2 of the base member 1 when the tongue 80 is inserted.

Next, a second embodiment of the present invention will be described in detail with reference to FIGS. 4 to 6.

This embodiment mainly has a clasp having a base member 101, a slider 110 capable of sliding on the base member in the longitudinal direction, and a clasp portion 124a, 124b installed to allow pivoting on the base member 101. Member 120, one end is fixed to the base member 101 by a rivet 135 and the other end is a leaf spring 130 that moves on the upper surface of the cam surface forming portion 126 of the clasp member 120 , The push button member 140 having an engaging rod 148 that can slide in combination with the curved bottom surface of the cam surface forming portion 126, the top and bottom cover members 170 and 160, and the tongue 180 are first Same as those of the examples.

In the second embodiment shown in Figs. 4 to 6, the parts that are compatible with the parts in the first embodiment are indicated as reference numbers made by adding 100 to the reference numbers of the first embodiment. Therefore, only parts different from the first embodiment will be mentioned later.

The shape of clasp member 120 is intended to have a cam surface forming portion 126 that is bent up and extruded to the rear. As mentioned above, one end of the leaf spring 130 moves the upper surface of the cam surface forming portion 126 to tilt the latch member counterclockwise relative to the front ends 127a and 127b of the latch member 120. This end of the leaf spring 130 does not split in two. On top of the leaf spring 130 and the clasp member 120, there is a push button member 140 that can slide the upper surfaces of the mouth walls 102a and 102b of the base member 101.

The push button member 140 has a bifurcated and rearwardly extending protrusions 142a and 42b and an engaging rod 148 passing laterally inside the rearmost portion of these protrusions 142a and 142b. Since the engaging rod 148 extends across the cam surface of the bottom surface of the camp surface forming portion 126 of the clasp member 120, when the push button member 140 slides backward, the clasp member 120 is a leaf spring ( Rotate upwards against the biasing force of 130).

The inner bottom surface of the protrusions 142a and 142b of the push button member 140 protrudes downwards to reliably guide the sliding movement of the push button member 140 over the upper end surfaces of the mouth walls 102a and 102b of the base member. . The holes 146a and 150b are drilled forward from the rear end faces of the protrusions 142a and 142b of the push button 140. One end of each coil spring 150a, 150b is drilled forward from the rear end surface of each hole 142a, 142b. One end of each coil spring 150a, 150b enters each of the holes 142a, 142b and the other end is extended by laterally extending ribs on the inner surface of the member 170 as evident in FIGS. Supported.

Therefore, the push button member 140 is always biased forward. Reference is made to FIGS. 5 and 6 to describe the second embodiment and operation. 5 shows a state in which the tongue 180 is engaged with the clasp member 120 through the tongue insertion hole 162. At this time, the clasp member 120 is rotated downward because the engaging rod 148 of the push button member 140 is in contact with the most indentation of the bottom cam surface of the cam portion 126 of the cam surface of the clasp member. .

As seen from the unit 102, the position of the clasps 124a and 124b of the clasp member 120 engaged with the cutouts 184a and 184b of the tongue 180 is higher. The push button 140 slides backward by applying a force to the front inclined portion 114 of the push button member with a finger.

Accordingly, as shown in FIG. 6, the engaging rod 148 moves back to come into contact with the rear surface of the cam surface of the cam surface forming portion 126 of the clasp member 12, and simultaneously lifts the cam surface forming portion 126. The clasp member 120 is rotated clockwise relative to the front end surfaces 127a and 127b against the biasing force of the leaf spring 130. When the clasp member is in this position, the clasp portions 124a and 124b are pulled out from the upper surface of the tongue 180, so that the engagement between the clasp portions 124a and 124b and the cutout portions 184a and 184b of the tongue 180 is lost. At the same time, the slider 110 is pushed forward by the coil spring 116 which has stored the restoring force until then. Therefore, the tongue 180 is pushed forward.
