ている。The device described in Japanese Utility Model Laid-Open No. 62-59549 is an example of such a device. A rail member having a rectangular cross section with a hollow cross section is provided with slits and a plurality of engaging projections in the vertical direction, while the rail is provided. The slide member movably arranged in the member is provided with a claw portion, and the claw portion is engaged with the engaging projection to position the slide member immovably in the vertical direction. The slide member is provided with a leaf spring for urging so as to maintain the engagement state between the claw portion and the engaging protrusion between the rail member and the claw portion when adjusting the height of the anchor member. The posture of the slide member is changed against the biasing force of the leaf spring so that the slide protrusion is disengaged, and the slide member is moved vertically as it is.

るが、そうすると大幅なコスト高となってしまう。However, in the above-mentioned conventional adjustable shoulder belt support device, the slide member and the leaf spring are brought into contact with the rail member, and when the posture of the slide member is changed, the leaf spring is generated. Since it is configured to be pressed against the rail member, when adjusting the height up and down as described above, slide the metals while they are pressed by the contact pressure corresponding to the biasing force of the leaf spring. Therefore, there is a problem in that the movement during adjustment is not always smooth and an unpleasant noise such as a scratching noise is generated. This problem can be solved to some extent by finishing both members that move relative to each other with high dimensional accuracy, but doing so would increase the cost significantly.

In addition to preventing prying between the slide member and the rail member while changing the posture of the slide member, the slide member is lifted upward against the belt tension acting on the anchor member. It was necessary to do, and the operation was troublesome compared to the downward adjustment.

れ、新たな高さ位置でショルダーベルトが支持される。When adjusting the support height of the shoulder belt downward, first, the anchor member is tilted or the like so that the upper end portion of the slide member is pushed into the inside of the rail member to change the posture of the slide member. Let Since the side wall portion of the slide member is engaged with the arm portion of the spring member, it is necessary to push the upper end portion of the slide member against the biasing force of the spring member. Along with this, the pair of arm portions of the spring member are brought closer to each other, the pair of claw portions are positioned inside the engagement protrusions of the rail member and their engagement is released, and the spring member and the slide member are moved up and down. Is acceptable. Therefore, the slide member and the spring member can be moved downward by keeping the posture of the slide member as it is and pulling down the anchor member. The slide member returns to the original posture according to the urging force of, and the claw portions of the spring member are separated from each other to be engaged with the engaging protrusions of the rail member, so that the shoulder belt is supported at the new height position.

る。On the other hand, when the support height of the shoulder belt is adjusted upward, the slide member is similarly pushed in to release the engagement between the claw portion and the engaging projection, and then the anchor member is lifted upward. The slide member and the spring member may be moved upward, and in that state, the pushing operation force of the slide member may be loosened so that the claw portion and the engagement protrusion are engaged with each other. Even if only the anchor member is pushed upward without moving, the pair of claw portions of the spring member move over the engaging projections while being brought close to each other according to the saw-tooth-shaped engaging projections, and the supporting height of the shoulder belt can be adjusted upward. It is possible.

がある。The height adjusting pitch of the slide member matches the pitch of the engaging projections, but the engaging projections have a saw-tooth shape that smoothly inclines toward the slit as it goes upward, so Even if the claw portion of the member is engaged with the sawtooth-shaped inclined portion, the claw portion is locked by the engaging protrusion while moving downward by a predetermined dimension smaller than the pitch, and further downward movement is prevented. . Therefore, the operation amount for moving the slide member up and down does not necessarily have to be an integral multiple of the adjustment pitch. Further, when the slide member is brought closer to the inner flat plate portion of the rail member according to the urging force of the spring member, another claw portion (second claw portion) engaged with a notch or the like formed in the rail member is formed. If the second claw of the spring member is provided on the slide member and the second claw of the spring member is engaged with the rail member to prevent the slide member from moving downward, the shoulder belt support height is increased. Also when adjusting the height upward, it is necessary to push in the slide member to release the engagement between the both claw portions and the rail member as in the case of adjusting the height downward.

Since a sliding member made of synthetic resin that can be moved in the vertical direction is interposed, the slide member that is also usually made of metal does not come into contact with the rail member that is usually made of metal, and the height adjustment is possible. The relative movement at the time is smoothly performed through the sliding member made of synthetic resin, and the generation of unpleasant noise such as rubbing noise is suppressed. Also with respect to the spring member, since the distal end portions of the pair of arm portions are brought into contact with the outer flat plate portion of the rail member via the sliding member, the movement is smooth and the generation of abnormal noise is suppressed. Also,
Since the sliding member made of synthetic resin is interposed in this way, the dimensional error is absorbed by the elastic deformation of the synthetic resin, the dimensional accuracy required for the rail member and the slide member is relaxed, and the device is inexpensive accordingly. Composed.

が容易となる。Further, while the pair of claw portions of the spring member engage with the plurality of engaging projections provided on the rail member to prevent the slide member from moving downward, the upper end portion of the slide member is at the upper end of the rail member. When it is pushed into the inside of the slide member, the pair of claw portions are positioned inside the engagement protrusions to release the engagement between the two and allow the slide member to move up and down. Since it is not necessary to provide another claw portion that directly engages with the rail member, and since such a spring member is easily composed of a wire spring or the like,
The structure can be simplified. Furthermore, when the downward movement of the slide member is prevented by only the pair of claw portions of the spring member,
Since the anchor member may be pushed up without pushing the slide member during the upward adjustment, the operation becomes easy.

ある。In this case, in this case, the load of the slide member is directly transmitted from the engaging portion to the claw portion, and is also transmitted from the claw portion to the rail member, so that the arm portion of the spring member, etc. The rail member reliably receives a large impact load applied to the slide member from the shoulder belt in the event of a vehicle collision, while the slide member is provided with another claw portion that directly engages with the rail member. It is possible to easily secure the strength capable of withstanding the above-mentioned load without increasing the mechanical strength required for the spring member. That is, in carrying out the first aspect of the invention, the slide member and the spring member may be engaged with each other via the latching portion of the spring member so as to be relatively immovable in the vertical direction. Since the load applied to the hooking part is transmitted to the claw via the arm, the spring member has a high mechanical force so that the claw does not come off the engagement protrusion of the rail member due to elastic deformation of the arm. Strength is required.
