Seatbelt device
First Claim
1. A seatbelt device, comprising:
- a pretensioner configured to cooperate with an anchor;
wherein said pretensioner includes a connector portion, andwherein the anchor is configured to be inserted into and engaged with said connector portion; and
wherein said connector portion includes a latch mechanism for engaging said anchor with the connector portion, and a disengagement prevention mechanism for preventing disengagement between said connector portion and said anchor in the event that a force acts upon said connector portion in a direction that urges disengagement of the connector portion and the anchor, wherein the disengagement prevention mechanism comprises an elastic prevention member configured to be attached to and fixed into position by the latch mechanism when the anchor is engaged with the connector portion.

Abstract
A seat belt device includes a lap anchor and connector assembly that are engaged by a latch pressed by a first latch spring. In the event that inertia force is applied to the connector assembly in a direction that tends to urge the disengagement of the connector assembly and the lap anchor, the latch tries to move in the direction of disengagement. The attempted movement causes retaining shoulder portions of the latch to abut against latch holding portions of a second latch spring, thereby preventing movement of the latch in the direction of disengagement. Thus, engagement of the connector assembly and the lap anchor is stable, and disengagement of the connector assembly and the lap anchor is prevented.
