Detailed Description
Several different preferred embodiments of the present invention will now be described with reference to the drawings, wherein like reference numerals represent like parts in the various figures. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1-2, the child growth device 100 of the present invention includes a first seat portion 110 and a second seat portion 120 pivotally connected to each other, the first seat portion 110 has a cavity 111, when the child growth device is folded, at least a portion of the second seat portion 120 is received in the cavity 111, when the child growth device is unfolded, the second seat portion 120 and the first seat portion 110 are coplanar to form a seat portion 18, and a safety belt hook 130 is installed on a side surface of the seat portion 18.
Specifically, as shown in fig. 1 and 2, the rear end of the first seat portion 110 and the front end of the second seat portion 120 are pivotally connected by a pivot, and in the unfolded state, the top surface of the first seat portion 110 and the top surface of the second seat portion 120 form the seat portion 18 for the child to seat. In order to ensure the ventilation of the seat portion 18, a plurality of rows of ventilation holes are formed on the top surface of the first seat portion 110 and the top surface of the second seat portion 120. In one embodiment, a supporting member 121 is optionally disposed on the bottom surface of the second seat portion 120, and the supporting member 121 can be made of soft material to increase the comfort of the seat, as shown in fig. 2 and 5.
As shown in fig. 1 and 2, the seat belt hook 130 is rotatably provided on the side of the joint of the first seat portion 110 and the second seat portion 120, i.e., the side of the seat portion 18. The seat belt hooks 130 are vertically positioned on both sides of the seat portion 18 when the seat is in the user's state, and the seat belt hooks 130 are rotated to the horizontal position without protruding from the top surface of the seat portion 18 when the seat is in the folded state. Specifically, the seat belt hook 130 may be pivotally connected to a side surface of the seat 18 by a pivot shaft between the first seat portion 110 and the second seat portion 120, or may be pivotally connected to a side surface of the seat 18 by another pivot pin.
Specifically, in the first embodiment, as shown in fig. 3, a mounting seat 181 is provided on a side surface of the seat portion 18 for mounting the seat belt hook 130, and a mounting hole is opened in the middle of the mounting seat 181 for passing through a rotating shaft or a rotating pin. The side of the seat portion 18 is further provided with a positioning protrusion 182, the positioning protrusion 182 is adjacent to the mounting seat 181, and optionally, the positioning protrusion 182 is a rib shape, and the extending direction of the positioning protrusion is a vertical direction. As shown in fig. 4, the belt hook 130 includes a mounting portion 131 and a hook portion 132, a positioning recess 133 is provided on the mounting portion 131 at a position corresponding to the positioning projection 182, and specifically, the positioning recess 133 is formed by a first projection 134 and a second projection 135 provided on the mounting portion 131.

When the positioning protrusion 182 is caught on the positioning recess 133, the first protrusion 134 and the second protrusion 135 are located at the left and right sides of the positioning protrusion 182, respectively. Specifically, the height of the first protrusion 134 is slightly shorter than the height of the second protrusion 135. When the seat belt hook 130 needs to be rotated and folded, the force is required to overcome the force of the first protrusion 134 on the positioning protrusion 182, so that the positioning protrusion 182 can be separated from the positioning recess 133 to rotate. The second protrusion 135 functions to prevent the belt hook 130 from being excessively rotated backward in the use state.

When the seat 100 is in the use state, the first seat portion 110 and the second seat portion 120 are unfolded to form the seat portion 18, the seat belt hook 130 is vertically positioned at both sides of the seat portion 18 and protrudes from the seat portion 18, and at this time, the positioning protrusion 182 of the seat portion 18 is clamped on the positioning recess 133 of the seat belt hook 130 to maintain the stable clamping state, as shown in fig. 1. When the seat 100 is not in use and needs to be folded, the second seat portion 120 rotates relative to the first seat portion 110 and is received in the cavity 111 of the first seat portion 110, and fig. 5 shows the folding process. Meanwhile, a rotational force may be applied to the belt hook 130 against the force of the first protrusion 134 of the belt hook 130 to the positioning protrusion 182, so that the positioning protrusion 182 is disengaged from the positioning recess 133, and the belt hook 130 may be rotated to a horizontal state, as shown in fig. 6. In this way, the second seat portion 120 is completely received by the first seat portion 110, and the harness hook 130 is horizontally received without protruding from the first and second seat portions 110 and 120. Therefore, the folded seat 100 has a small size, thereby saving the storage space, and the seat belt hook 130 does not protrude out of the seat, thereby further reducing the size and increasing the safety factor.
Fig. 7-9 show other embodiments of the child growth device of the present invention, for example, the first seat portion 110 and the second seat portion 120 may be covered with a soft cloth 191 or a pad to increase the comfort or aesthetic feeling of the seat. In the stowed state, the positioning webbing 192 may be employed to bind the folded first seat portion 110 and the second seat portion 120; or in the storage state, the safety belt hook 130 is rotated to the vertical open state, and then a hanging belt 193 is connected for the user to move and carry.
