重を車体側で担持させるよう構成されている。 Conventionally, there is a seatbelt locking device for automobiles as shown in Japanese Utility Model Application Laid-open No. 49-77624. In this configuration, a rail on the floor panel, a seat that is movable back and forth on the rail, and a seatbelt anchor part that is rotatably supported on the seat are provided. The anchor portion rotates and engages with a support device on the floor panel, so that the load on the seat belt is carried by the vehicle body.

ないものである。 By the way, if the seat is configured to rotate around a horizontally eccentric vertical axis and change the seating direction forward or backward, and if this seat has a seat belt, the part that allows the seat to rotate Although it is not preferable to apply an external force to the seat, this part is eccentric from the seat and is therefore susceptible to external forces from the seat. Therefore, it is desirable that the tension force of the seatbelt in such a case be supported by the locking device as described above, but the device is installed on one side of the seat that moves back and forth. This cannot be easily applied to seats of this type.

る。 On the other hand, in each state where the seating direction is changed from forward to backward,
A pair of locked members 32, 32 are provided on the floor panel 1, each of which can be locked to and removed from the locking member 26. This locked member 32 has a fixing piece 33 that is fixed to the floor panel 1 together with the leg part 12 by the bolt 13, and a locking ring 34 that is welded to this fixing piece 33. The locking portion 29 and the locking ring 34 are configured to engage with each other by rotation.

への負荷が抑制されて強度上有益である。 According to this invention, in a seat device in which the seating direction with respect to the seat can be changed back and forth by rotating the seat, a locking member is rotatably supported on the seat, and a locking member is attached to a rotating end of the locking member. Seat belts are connected,
On the other hand, since the vehicle body is provided with a pair of locked members that can be respectively engaged and detached from the locking member when the seating direction is changed from front to back, the tension force of the seat belt 8 is applied to the fixed side of the vehicle body. The seat 7 is supported by the locked member 32 provided on the seat 7.
The load on the connecting portion between the base 3 and the rotating member 6, which allows the rotary member to rotate, is suppressed, which is beneficial in terms of strength.
