6. The child car seat according to claim 4, wherein:
8. The child car seat according to claim 7, wherein:
11. The child car seat according to claim 4, whereina plane including an operation direction of the operation member and a plane including an operation direction of the deregulating member are perpendicular to each other.

The pedestal 50 includes a base part 51 to be placed on a seat part la of the vehicle seat 1, as shown in FIG. 3, and a standing part 52 standing from the base part 51 so as to be opposed to a back part 1b of the vehicle seat 1, as shown in FIG. 3. The base part 51 has a front surface 51a, side surfaces (lateral surfaces) 51b and a bottom surface 51c (see, FIG. 1 and so on). On the other hand, the seat body 20 has a seat part 21 supported on the base part 51 such that the seat body 20 can be slid with respect to the base part 51 of the pedestal 50, and a backrest part 22 extending from the seat part 21.
Next, the pedestal 501 is described in detail. As shown in FIG. 3, the pedestal 50 can be mounted on the vehicle seat 1 by means of a seatbelt 5 of a vehicle, which has a waist belt 6a and a shoulder belt 6b. Thus, the standing part 52 of the pedestal 50 is provided with two lock-off devices 79 for clamping the shoulder belt 6b of the seatbelt 5. The lock-off devices 79 are positioned away from each other in the lateral direction, so that the lock-off devices 79 can be adapted to two inclined directions of the shoulder belt 6b. As shown in FIG. 3, the shoulder belt 6b clamped by the lock-off devices 79 obliquely transverses the standing part 52 of the pedestal 50.
The pedestal 50 also has a waist-belt guide part 70 that guides the waist belt 6a. The waist-belt guide part 70 will described in detail below.
The operation-amount adjusting mechanism 40 includes: a contacting and regulating member 42 which can be brought into contact with the operation member 31 of the lifting mechanism 30; and a deregulating member 41 connected to the contacting and regulating member 42, the deregulating member 41 being configured to move the contacting and regulating member 42 when operated. The contacting and regulating member 42 can be moved between: a first position pa1 (see, FIG. 21) at which the contacting and regulating member 42 is in contact with the operation member 31 of the lifting mechanism 30 so as to regulate the movement of the operation member 31, such that an operation amount of the operation member 31 is not less than the first operation amount but is less than the second operation amount; and a second position pa2 (see, FIG. 22) at which an operation amount of the operation member 31 is allowed to be not less than the second operation amount.
When operated, the deregulating member 41 allows the movement of the contacting and regulating member 42 from the first position pa1 to the second position pa2.
Further, the deregulating member 41 is disposed in the vicinity of the operation member 31. Thus, it is very easy to operate the operation member 31 and the deregulating member 41 so as to move the seat body 20 to the turning position. In addition, since the deregulating member 41 is disposed in the vicinity of the operation member 31, when the seat body 20 is moved to the turning position, it can be efficiently prevented that the user fails to operate the deregulating member 41.
Moreover, since the plane (vertical plane) including the operation direction of the operation member 31 and the plane (substantially horizontal plane) including the operation direction of the deregulating member 41 are perpendicular to each other, the operation direction of the operation member 31 and the operation direction of the deregulating member 41 are oriented differently from each other. More strictly, the swinging axis line dl of the operation lever 31 and the swinging axis line d3 of the deregulating member 41 are substantially perpendicular to each other, whereby the operation direction (upward direction) of the operation lever 31 and the operation direction (substantially lateral direction) of the deregulating lever 41 are substantially perpendicular to each other. Thus, it can be efficiently prevented that the deregulating member 41 is accidentally operated when the operation member 31 is operated, or that the operation member 31 is accidentally operated when the deregulating member 41 is operated.
As described above, the child car seat 10 can be mounted on the vehicle seat 1 by fixing the pedestal 50 onto the vehicle seat 1 with the use of the seatbelt 5 provided on the vehicle seat 1. At this time, the base part 51 of the pedestal 50 is placed on the seat part la of the vehicle seat la, and the standing part 52 of the pedestal 50 is opposed to the back part 1b of the vehicle seat 1.
Herebelow, the structure and the operation of the waist-belt guide part 70 are described in more detail. As shown in FIG. 24, the waist-belt guide part 70 includes a front guide part 71 extending on the front surface 51a of the base part 51, and side guide parts 72 continuous to the front guide part 71 and extending on the side surfaces 51 of the base part 51. The waist-belt guide part 70 is configured to guide the waist belt 6a on the base part 51. The front guide part 71 and the side guide part 72 are formed to have a groove-like shape as a whole. An upper edge UE defining the front guide part 71 and the side guide parts 72 from above, and a lower ledge LE defining the front guide part 71 and the side guide parts 72 from below, are substantially defined by steps (differences).
According to such a waist-belt guide part 70, the waist belt 6a can be stably held at substantially a constant position. In this manner, by surrounding the base part 51 of the pedestal 50 by the waist belt 6a from the front surface 51a and the side surfaces 51b, the child car seat (child car seat body 11) can be stabilized, particularly in the front and back direction, on the vehicle seat 1.
