Child safety seat
A child safety seat includes a seat base having shell body, and a support leg connected with the shell body. The support leg includes a tubular segment, a support portion, a fastener connected with the tubular segment and the support portion, and a cushioning structure disposed adjacent to the fastener, wherein the cushioning structure is configured to block displacement of the fastener so that the support portion is locked in position relative to the tubular segment, and to deform or break as a result of a displacement of the fastener into the cushioning structure when a substantial force is applied that forces the tubular segment to move relative to the support portion.
1. A child safety seat comprising:
a seat base having a shell body;
a support leg connected with the shell body at a pivot connection, the support leg being rotatable relative to the shell body between a deployed position extending downward from the shell body for providing support, and a folded position close to the bottom of the shell body, wherein the support leg includes:
a tubular segment;
a support portion having a distal end capable of resting in contact against a floor of an automobile vehicle;
a fastener connected with the tubular segment and the support portion; and
a cushioning structure disposed adjacent to the fastener,
wherein the cushioning structure is configured to block displacement of the fastener so that the support portion is locked in position relative to the tubular segment, and to deform or break as a result of a displacement of the fastener into the cushioning structure when a substantial force is applied that forces the tubular segment to move relative to the support portion.
2. The child safety seat according to claim 1 , wherein the support portion is a foot portion affixed with a lower end of the tubular segment, and the support portion being in contact on a floor surface of an automobile vehicle when the child safety seat is installed in the automobile vehicle and the support leg is in a deployed state.
3. The child safety seat according to claim 2 , wherein the tubular segment is fixedly assembled with the foot portion via the fastener.
4. The child safety seat according to claim 2 , wherein the tubular segment includes a first and a second hole spaced apart from each other along a lengthwise axis of the support leg, the fastener is respectively engaged through a third hole of the foot portion and the first hole of the tubular segment, and the cushioning structure includes cushion portion disposed between the first and second hole.
5. The child safety seat according to claim 4 , wherein the cushion portion is a material portion of the tubular segment located between the first and second hole.
6. The child safety seat according to claim 4 , wherein the cushion portion includes a narrow slot that extends along the lengthwise axis of the support leg, and connects with the first and second holes.
7. The child safety seat according to claim 6 , wherein the narrow slot has a width smaller than a width of the fastener.
8. The child safety seat according to claim 4 , wherein the cushioning structure includes a plurality of ribs and one or more slit alternately disposed parallel to one another along the lengthwise axis in the cushion portion between the two first and second holes.
9. The child safety seat according to claim 8 , wherein the cushioning structure further includes a narrow slot that connects with the first and second holes and cuts perpendicularly across the ribs.
10. The child safety seat according to claim 8 , wherein the slit has a dimension along the lengthwise axis that is smaller than the second hole.
11. The child safety seat according to claim 1 , wherein the fastener is a pin or a rivet.
12. The child safety seat according to claim 1 , wherein the support portion is a foot portion affixed with a lower end of the tubular segment, and the foot portion includes a slot formed at a bottom thereof, and a display window formed at a side thereof, and the support leg further includes an indicator member movably connected with the foot portion and operable to indicate whether the support leg is folded or deployed against a floor of an automobile vehicle.
13. The child safety seat according to claim 1 , wherein the tubular segment is sleeved into the support portion and the cushioning structure is positioned on the tubular segment.
14. The child safety seat according to claim 1 , wherein the support portion is a rigid block configured to contact against a floor of an automobile vehicle.
15. A child safety seat comprising:
a seat base having a shell body;
a support leg connected with the shell body, wherein the support leg includes:
a tubular segment;
a support portion having a distal end surface capable of resting in contact against a floor of an automobile vehicle, the distal end surface having a slot;
a fastener connected with the tubular segment and the support portion; and
a cushioning structure disposed adjacent to the fastener, the cushioning structure blocking displacement of the fastener so that the support portion is locked in position relative to the tubular segment, and the cushioning structure deforming or breaking as a result of a displacement of the fastener into the cushioning structure when a substantial force is applied that forces the tubular segment to move relative to the support portion; and
an indicator member connected with the support portion and configured to indicate whether the support leg is properly installed against the floor of the automobile vehicle, wherein the indicator member extends outward through the slot when the distal end surface of the support portion is out of contact with the floor, and the indicator member displaces toward an interior of the support portion when the distal end surface rests in contact against the floor.
16. The child safety seat according to claim 15 , wherein the indicator member is pivotally connected with the support portion.
17. The child safety seat according to claim 15 , wherein the tubular segment includes a first and a second hole spaced apart from each other along a lengthwise axis of the support leg, the fastener is respectively engaged through a third hole of the foot portion and the first hole of the tubular segment, and the cushioning structure includes cushion portion disposed between the first and second holes.
18. The child safety seat according to claim 17 , wherein the cushion portion is a material portion of the tubular segment located between the first and second hole.
19. The child safety seat according to claim 17 , wherein the cushion portion includes a narrow slot that extends along the lengthwise axis of the support leg, and connects with the first and second holes.
20. The child safety seat according to claim 17 , wherein the cushioning structure includes a plurality of ribs and one or more slit alternately disposed parallel to one another along the lengthwise axis in the cushion portion between the two first and second holes.
