Therefore, the seatbelt retractor 40 is equipped with a seatbelt)B.
The seatbelt buckle 301d is a device that forcibly winds up and houses the seatbelt (B) that is pulled out from the seatbelt retractor 40.The seatbelt buckle 30 has a shape shown in Fig. 2. is formed.

In other words, the seatbelt buckle 30 is a seatbelt)
A fastener part 31 to which the tip of B can be attached, a front arm part 32 extending from the fastener part 31, and a rear leg part formed integrally with the front arm part 32 and extending backward and upward from its base 32a. 33, and is formed into a substantially V-shape on the side.

As shown in FIGS. 2 and 4, this seat belt buckle 30 is rotatably attached to the front lower part of the bracket 51 from the connecting member 52 attaching part with a stepped bolt 54, and the rear arm part 33 The tip of the connecting member 52 is in contact with the rear lower end 52a of the connecting member 52.

Furthermore, one end of the stepped bolt 54 is secured to the bracket 51 and the other end is connected to the seat belt buckle 30.
A spring 55 that is engaged with the front arm portion 32 of the front arm 32 is interposed.

As a result, the seatbelt buckle 30 is urged forward and downward, and the tip of the rear arm 33 is connected to the connecting member 52.
Resiliently abuts against the rear lower end 52a of.

As a result, when the seatback 20 is tilted forward, the seatbelt buckle 30 rotates in the direction of the second arrow hole shown in the figure, and its fastener 31 and front arm 32 move along one side 11 of the seat cushion 10. To position.

Further, when the seat back 20 is raised rearward from this state, the connecting member 52 that rotates accordingly pushes the rear arm portion 33 of the seat buckle 30 downward, and the fastener portion 31 and the front arm The portion 32 moves upward to the state shown in FIG.

That is, the seat belt buckle 30 is attached to the seat back 2.
It undulates according to the undulation of 0.

On the other hand, as shown in FIG. 3, the seat belt retractor 40 has a belt retractor 41, and the attachment of the belt retractor 41 is integrally formed with the base end 41a, and the seatbelt retractor 40 has a belt retractor 41 that is mounted rearward and upward from the base end 41a. The rear arm portion 42 extends in a curved manner, and is formed into a generally V-shaped side surface.

This seat belt retractor 40 is rotatably attached to the front lower part of the bracket 51 from the connecting member 52 attachment part with a stepped bolt 56, and the tip of the rear arm part 42 is attached to the rear lower end of the connecting member 52. 52a.

Further, the stepped bolt 56 is similar to the stepped bolt 54 shown in FIGS. 2 and 4, and has one end secured to the bracket 51 and the other end secured to the seat belt retractor 40.
A spring (not shown) that is engaged with the inside of the belt winding portion 41 is interposed.

As a result, the seatbelt retractor 40 is pressed forward and downward in exactly the same manner as the seatbelt buckle 30, and the tip of the rear arm 42 is elastically pressed against the rear lower end 52a of the connecting member 52. are in contact.

As a result, the seatbelt winding device 40
It undulates integrally with the seat belt buckle 30 according to the undulations of 0.
