Multi-point seat belt assembly
View Patent ↗A multi-point seat belt assembly has a buckle assembly, two webbing-locking mechanisms, two main webbings, and at least one retractor. The buckle assembly has a buckle member and a tongue member detachably inserted into the buckle member. The webbing-locking mechanisms are mounted on the buckle assembly, and each webbing-locking mechanism has a connecting member and a movable member mounted moveably on the connecting member. The connecting members of the two webbing-locking mechanisms are connected respectively with the buckle member and the tongue member. The main webbings are mounted respectively through the webbing-locking mechanisms and each main webbing has an end. The at least one retractor is connected with the ends of the two main webbings.
1. A multi-point seat belt assembly comprising:
a buckle assembly comprising
a buckle member; and
a tongue member detachably inserted into the buckle member;
two webbing-locking mechanisms mounted on the buckle assembly, each webbing-locking mechanism comprising a connecting member and a movable member mounted moveably on the connecting member, wherein the connecting members of the two webbing-locking mechanisms are connected respectively with the buckle member and the tongue member;
two main webbings mounted respectively through the webbing-locking mechanisms, each main webbing having a first end and a second end; and
at least one retractor connected with the first ends of the two main webbings;
wherein each one of the two main webbings has a tension to change a position of the movable member of a respective one of the two webbing-locking mechanisms relative to the connecting member of the webbing-locking mechanism to lock the main webbing in a unidirectional manner by the corresponding webbing-locking mechanism such that the first end and the second end form an angle larger than or equal to 90 degrees to provide at least four securing points;
wherein the connecting member of each webbing-locking mechanism has a through hole defined through the connecting member, a front side, and a rear side opposite the front side;
wherein the movable member of each webbing-locking mechanism comprises
a front portion located at the front side of the connecting member of the webbing-locking mechanism and having a limiting protrusion formed on and protruding from the front portion and extending slidably in the through hole in the connecting member; and
a rear portion located at the rear side of the connecting member of the webbing-locking mechanism, and the front portion and the rear portion have a height difference between each other;
wherein each main webbing passes through the through hole in the connecting member of a corresponding one of the webbing-locking mechanisms via a space defined between the connecting member and a front end of the front portion of the movable member of the corresponding webbing-locking mechanism and passes a bottom of the rear portion of the movable member of the corresponding webbing-locking mechanism.
2. The multi-point seat belt assembly as claimed in claim 1 further comprising two auxiliary webbings connected respectively with the buckle member and the tongue member.
3. The multi-point seat belt assembly as claimed in claim 2 , wherein each auxiliary webbing has an adjusting member mounted on the auxiliary webbing.
