<p>PROBLEM TO BE SOLVED: To pertinently restrain an occupant on a vehicle so as to properly reduce impact on his body upon occurrence of collision.SOLUTION: In a case where an age estimation part 113 estimates the age of an occupant as a predetermined age or older, when a buckle switch 104 detects change in webbing 5 from an un-equipped mode to an equipped mode, a control device 103 reduces tension for removing slack of the webbing 5 to weak tension than that in a case where the age estimation part 113 estimates the age of the occupant as an age less than the predetermined age. In a case where a collision prospecting part 112 determines that a possibility of occurrence of collision of the vehicle is predetermined value or more, the control device 103 increases tension for winding the webbing 5 to stronger tension than that in a case where the age estimation part 113 estimates the age of the occupant as an age less than the predetermined age.</p> |
