Description

  The present invention relates to a seat belt buckle housing structure.

When the automobile seat is a seat for three people, a seat belt for three people is required. Therefore, seat belt buckles that fit the tongues of the seat belts arranged on the left and right side walls are respectively arranged at the ends of the left and right seat surfaces near the center of the vehicle, and the seat for the central seat is taken from the belt winding device fixed to the ceiling. A pair of seat belt buckles, which are configured to pull out the belt and are individually fitted with a pair of tongues of the seat belt, are arranged on both sides of the seat surface of the central seat.
The one seat belt buckle for the left and right seats and the one seat belt buckle for the central seat are arranged in close proximity. Accordingly, it is sufficient to pass two seat belt buckles through two holes formed in the seat cushion seats on both sides of the center seat. For example, as disclosed in Patent Document 1, in the seat width direction, When two seat belt buckles are arranged, the width of the seat cushion seat surface becomes shorter. Therefore, as disclosed in Patent Document 2, two seat belt buckles are arranged in the front-rear direction of the seat to widen the seat surface of the seat cushion in the seat width direction.
Conventionally, in such a seat belt buckle housing structure, a first seat belt buckle and a second seat belt buckle arranged adjacent to each other in the front and rear are connected and integrated by a buckle holder.
