る。 The rotatable table 5 rotates horizontally and locks the lock member 10.
When the vertical plate 10b faces the striker 4 of the fixed table 3, the lower part of the vertical piece 10b swings toward the rotation center of the rotatable table by the elastic force of the spring 12, and the striker 4 enters the lock hole 13 of the vertical piece 10b. When engaged, the rotary table 5 is automatically locked with respect to the fixed table 3, and the claw portion 14 is placed slightly apart below the engagement hole 4a of the striker 4 so as to be able to engage with it. Then, the seat belt 8 is pulled forward with excessive tension, and the forward load is transmitted to the rear end of the rotatable table 5 via the anchor portion 8a, causing the vicinity of the seat belt attachment portion of the rotatable table 5 to curve upward. When deformed, the lock member 10 is displaced upward and the claw portion 14 is inserted into the occlusion hole 4a of the striker 4, and the claw portion 14 and the occlusion hole 4a engage with each other.
The load on the rotatable table 5 is caused by the claw portion 14 and the occlusal hole 4a.
is transmitted to the fixed table 3 via the occlusal part with the
By deforming the striker 4 and the locking member 10, the load on the rotatable table 5 can be absorbed.

することができる。 Now, the seatbelt 8 worn by the occupant in the vehicle is pulled forward with excessive tension, and a concentrated load is applied to the rear end of the rotatable table 5 via the anchor portion 8a of the seatbelt 8. When the vicinity of the belt attachment part deforms upward, the locking member 10
is displaced upward and the claw portion 14 of the locking member 10 and the engagement hole 4a of the striker 4 engage with each other, so that the concentrated load on the movable table 5 is transferred to the fixed table via the engagement area between the striker 4 and the locking member 10. The load on the rotatable table 5 can be received by both tables 3 and 5 and effectively absorbed by the deformation of the lock member 10 and the deformation of the striker 4.

によつて吸収することができる。 Due to the interlocking effect between the striker 4 and the locking member 10, that is, due to the synergistic effect of the bending rigidity of the striker 4 and the bending rigidity of the locking member 10, the rigidity of the rotatable table 5 in the load direction is substantially increased. This improves the strength characteristics of the rotatable table without increasing its weight, size, or cost, and also reduces the load applied to the rotatable table 5 by the seat belt 8 to the locking mechanism. It can be absorbed by twisting.
したがつて、シートベルト取付装置の回転側部

全性を高めることができる。 Therefore, it is possible to reduce the weight and dimensions of the rotating side member of the seat belt attachment device and ensure its strength characteristics, thereby increasing the safety of the seat belt wearer.
また、可転テーブル５を回転シートＳが前向き
若しくは後向きとなつた状態でロツクするロツク
機能を確保することができる。 Furthermore, a locking function for locking the rotatable table 5 with the rotary seat S facing forward or backward can be ensured.

することができる。 Since the present invention is constructed as described above, it is possible to ensure the locking function of locking the rotatable table of the rotary seat in a predetermined position, and also to prevent excessive load from being applied to the rotatable table due to the tension of the seat belt. Then, this load is transmitted to the fixed table via the lock mechanism, and the rigidity of the fixed table is used to suppress excessive deformation of the rotatable table and absorb the load, thereby reducing the weight, size, and cost of the rotatable table. The rigidity of the rotatable table in the load direction can be substantially improved by eliminating this, and the load applied to the rotatable table through the seat belt anchor can be efficiently absorbed by the lock mechanism. can.
