Abstract

In a lift-up buckle device, a slider and a shoe move forward and a buckle is moved to a stowed position. The shoe impacts against a protruding portion at a lower portion of a damper and interferes with a housing via the lower portion of the damper. Thus, the forward movement of the slider and shoe is stopped, while the damper absorbs an impact against the slider and shoe. Therefore, an amount of the impact against the slider and shoe that is absorbed by the damper may be increased by the protruding portion, and the damper may absorb the impact against the slider and shoe effectively.

First claim

What is claimed is:

1. A seatbelt moving device comprising:
a moving body that structures a seatbelt apparatus and is moved such that a seatbelt is moved;
a stopping body that stops movement of the moving body; and
an absorbing body at which a protruding portion that protrudes from a part of a face of the absorbing body facing the moving body is provided, the moving body interfering with the stopping body via the protruding portion, and the absorbing body absorbing an impact against the moving body,
wherein a cross-sectional area of a distal side portion of the protruding portion that is orthogonal to a protrusion direction of the protruding portion is smaller than a cross-sectional area of a base side portion of the protruding portion orthogonal to the protrusion direction,
further comprising a contacting body that makes contact with the absorbing body, wherein the absorbing body is fitted to the stopping body and the contacting body is assembled to the stopping body such that the absorbing body is assembled to the stopping body by the contacting body restricting movement of the absorbing body.

2. The seatbelt moving device according to claim 1 , wherein a cross-sectional area of the protruding portion orthogonal to a protrusion direction of the protruding portion decreases along the protrusion direction.

3. The seatbelt moving device according to claim 1 , wherein the protruding portion is a continuous solid body along the cross-sectional area of a distal side portion.

4. A seatbelt moving device comprising:
a moving body that structures a seatbelt apparatus and is moved such that a seatbelt is moved;
a stopping body that stops movement of the moving body; and
an absorbing body at which a protruding portion that protrudes from a part of a face of the absorbing body facing the moving body is provided, the moving body interfering with the stopping body via the protruding portion, and the absorbing body absorbing an impact against the moving body,

wherein a cross-sectional area of a distal side portion of the protruding portion that is orthogonal to a protrusion direction of the protruding portion is smaller than a cross-sectional area of a base side portion of the protruding portion orthogonal to the protrusion direction, further comprising a drive screw that drives the moving body.
