<p>PROBLEM TO BE SOLVED: To provide a seat belt device capable of suppressing movement of an occupant with preventing increase of belt load applied to the occupant in a vehicle collision. SOLUTION: A pre-tensioner 600 for remove looseness of a webbing 70, an energy absorbing mechanism 100 for feeding the webbing when the load exceeds a predetermined load, and a tongue plate 505 for fastening the webbing are combined. Even when the energy absorbing mechanism operates to feed the webbing, the tongue plate 505 for fastening the webbing prevents forward movement of the waist part of the occupant. Therefore, increase of the load to the upper part of the occupant is reduced, and secondary collision of the lower part can be prevented.</p> |
