噛合している。As shown in FIGS. 5 and 6, the lumbar support portion 8 is attached to the seat back 3 via an angle adjustment mechanism 31 so as to be adjustable in angle. The angle adjustment mechanism 31 is the horizontal rod 18
Ratchet wheel 3 fixed by arc welding etc.
2 and the side? Two ends of the frame 17b have pivot pins 34 on the outside.
A lock plate 3 is rotatably supported by a lock plate 3 and has teeth 35 formed at the other end to mesh with the ratchet wheel 32.
3. A rotation restriction plate 37 in which a cutout groove 38 is formed for setting a rotatable range is fixed to the ratchet wheel 32, and the rotation restriction plate 37 of the horizontal rod 18 is fixed to the ratchet wheel 32.
A cam-shaped first link 41 is rotatably fitted in a position close to the first link 41, and one end of a second link 42 is pivotally supported by a pin 43 to the free end of the first link 41. The other end of the link 42 is rotatably supported by a pin 39 provided on the side of the lock plate 33 adjacent to the teeth 35,
A tension spring 44 tensioned between the lock plate 33 and the horizontal rod 18 is biased so that the teeth 35 of the lock plate 33 are normally engaged with the ratchet wheel 32. The sum of the length Ll between the pivot points of the first link 41 and the length R2 between the pivot points of the second link 42 is determined by the outer diameter R1 of the ratchet wheel 32 and the tooth from the fin 39 of the lock plate 33. 35
When the teeth 35 of the lock plate 33 engage with the ratchet wheel 32, the first and second links 41 and 42
On the other hand, when the first and second links 41 and 42 become straight, the teeth 35 of the lock plate 33 are released from the meshing state with the ratchet wheel 32. Ru. Reference numeral 43a indicates a pivot point between the first link 41 and the second link 42, that is, a tip protrusion of the bottle 43, and this protrusion 43a is inserted into the notch groove 38 of the rotation regulating plate 37, and The first one at one end of the groove 38
The rotation of the first link 41 stops when the protruding part 43a comes into contact with the regulating part 37a, and then the first and second glues 41 and 42 gradually become straight, and cross the dead point. Stopper 4 provided on lock plate 33
6, the second link 42 stops rotating at the position where one end of the second link 42 comes into contact with the second link 42, the meshing state between the teeth 35 of the lock plate 33 and the ratchet wheel 32 is released, and the lumbar support part 8 rotates. The lumbar support part 8 is rotated toward the back side of the seat back 3 about the horizontal rod 18 as shown in FIG. 2 by the biasing force of the movable spring 23. Next, as the protruding part 43a comes into contact with the second regulating part 37b at the other end of the notch groove 38, the first and second links 41 and 42 gradually bend to the opposite side beyond the dead point. It is held by the biasing force of the tension spring 44, and the teeth 35 of the lock plate 33
engages with the ratchet wheel 32 again. In the present embodiment, the protruding portion 43a abuts the first regulating portion 37a with the upper portion of the lumbar support portion 8 moved forward by a predetermined angle, and the lumbar support portion 8 is moved toward the back side of the seat back 3. The notch groove 38 of the rotation regulating plate 37 is formed so that the protruding portion 43a contacts the second regulating portion 37b in a substantially horizontally protruding state, and the lumbar support portion 8 is in a horizontal state than in a folded state. The ratchet wheel 32 and the teeth 35 of the lock plate 33 mesh in the rotation range up to a state where the lumbar support part 8' is stored in the space 7 of the seat back 3 and the upper part of the lumbar support part 8' slightly protrudes from the front side of the seat back 3. In addition, when the lumbar support part 8 moves forward, the lock plate 33 swings, but when it moves backward, the engaged state is not released, and the teeth 3 of the lock plate 33 It meshes with the ratchet wheel 32.

る事も出来る。The above is the configuration of an embodiment of the seat structure for a vehicle or the like according to the present invention. The lumbar support part 8 can be slid in the vertical direction along the vertical direction to adjust the vertical position according to the physique and preference of the seated person. From this state, if the lumbar support part 8 is rotated forward by the angle adjustment mechanism 31, the lumbar vertebrae can be adjusted. The upper part of the support part 8 can be held with the upper part protruding forward, or the upper part of the lumbar support part 8 can be held with the upper part protruding backward. 14, and in this state, tilt the lumbar support part 8 toward the back side of the seat back 3 using the angle adjustment mechanism 31 and hold it in a substantially horizontal state. 8 can be used as a footrest in a substantially horizontal state, and by arbitrarily selecting the inclination angle of the lumbar support part 8, the relative relationship with the side part of the seatback 3 changes, and the seatback 3 can be varied in various ways, and for example, a packet type sheet 1 can be formed.
