In this state, the crotch buckle 76 The leaf spring 138 (the state shown in FIG. 9(A)) is inserted into the notch of the coupling shaft 128. 140, and the crotch buckle 76 is engaged with the coupling shaft 128. It is used for holding purposes.

[0034] When using the child seat 10 as a junior seat, the seat cushion Since only the seat cushion 18 is used, the crotch buckle 76 is separated from the seat cushion 18. must be removed. Below, seat cushion 1 of crotch buckle 76 The operation for leaving from 8 will be explained.

[0035] First, the crotch buckle 76 is pushed forward from the state shown in FIG. The state shown by the solid line in 8(A) is reached. From this state, remove the crotch buckle 76. Push the hook 120 of the crotch buckle 76 away from the coupling shaft 128. (state shown by the two-dot chain line in FIG. 9(A)). Next, as shown in FIG. 9(B) Pass the crotch buckle 76 under the coupling shaft 128 as shown in Fig. 9 ( Pull out the crotch buckle 76 as shown in C). This allows the The hitch buckle 76 is removed from the drum 122 and the drum 122 is A state in which the cover 130 closes approximately half of the opening 116 due to the biasing force of the tension coil spring. becomes. As a result, the crotch buckle 76 is separated from the seat cushion 18. Ru.

[0036] (Side support opening/closing mechanism) When a child gets on or off, the crotch buckle 76 is folded forward and the side support 1 18 must be opened to the maximum to improve ease of getting on and off. As shown in Figure 10, An intermediate gear 142 is pivotally supported on the front side of the side support 118. this The middle gear 142 meshes with the worm gear 144. Pair of side supports 1 Eighteen worm gears 144 are fixed to one shaft 146. A small gear 148 is fixed to the axially intermediate portion of the foot 146 . Therefore, the small gear 148 and worm gear 144 rotate with shaft 146. Small gear 148 is meshed with the crotch gear 132 of the drum 122. Therefore, the crotch The crotch gear 132 rotates according to the tilt angle of the buckle 76, and this rotational force is small. One through gear 148, shaft 146, worm gear 144 and intermediate gear 142. This configuration is transmitted to the paired side supports 118.

[0037] Further, an engagement arm 150 is located near the stopper 136 of the crotch gear 132. It is arranged so that it can rotate. The engagement arm 150 has a base portion 150A and a contact portion 150B. and an engaging portion 150C. The base 150A is pulled up by the tension coil spring 152. It is urged away from the ram 122.

[0038] In addition, if the rail 114 of the seat cushion 18 is engaged with the lower groove 86, In this case, the contact portion 150B of the engagement arm 150 is connected to the fixed portion 68 of the seat back 16. The support wall 88 is in contact with the support wall 88 . However, when the rail 114 has the upper groove 84 and the middle groove 85, the contact portion 150B of the engagement arm 150 is engaged with the fixed portion 6 The support wall 88 of No. 8 is prevented from coming into contact with the support wall 88 of No. 8. That is, the contact portion 150B and Support walls 880 are spaced apart.

[0039] As shown in FIG. 10, the support wall 88 and the contact portion 150B are in a spaced apart state. In this case, the engaging portion 150 of the engaging arm 150 is C does not engage with the stopper 136 of the crotch gear 132. Therefore, the dragon The arm 122 cannot be rotated beyond the position where the stopper 136 and the contact portion 150B engage with each other. becomes possible. However, the support wall 88 and the contact portion 150B are in contact with each other. In this case, the engaging portion 150C of the engaging arm 150 is biased by the biasing force of the tension coil spring 152. is pressed by the contact portion 150B against the come to a matching position. Therefore, the amount of rotation of the drum 122 is regulated.

[0040] To explain further, the rail 114 of the seat cushion 18 is connected to the seat back 16. In the state where it is engaged with the upper groove 84 (the state where the seat surface is the highest), the strut Since the upper part 136 and the contact part 150B do not interfere with each other, the crotch buckle 76 It is tilted toward the seat back 16 and is in the position shown by the solid line in FIG. Therefore, The child's infant belts 72, 73 are in an optimal state of being worn. On the other hand, the seat cushion The state in which the rail 114 of the seat back 18 is engaged with the groove 86 in the lower part of the seat back 16 ( When the seat surface is at its lowest position), the contact portion 88 interferes with the stopper 136. position, the amount of tilting of the crotch buckle 76 toward the seat back 16 is reduced. It is located at the position indicated by the dashed line in FIG. Therefore, even in this case, the child The infant belts 72 and 73 are in an optimal state. However, this level of clock Depending on the amount of tilting of the buckle 76, the opening of the side support 118 is small.

[0041] Then, the crotch buckle 76 is separated from the seat cushion 18 and the When used as an automobile seat, the crotch buckle 76 is shown by the two-dot chain line in FIG. tilted to a position where Therefore, in this state, the side support 118 is Open to the position indicated by the two-dot chain line to fit the physique of an infant (5 years old or older).
