Child safety seat assembly
A child safety seat assembly includes a shell body for defining a support base attachable to a child seat, a leg frame extendible downward from a bottom of the shell body, and a cushion part. The leg frame includes a first and a second tube segment attached with each other, the first tube segment being affixed with a fastener. The cushion part is affixed in the second tube segment adjacent to the fastener, and is formed as an integral hollow body including a first, a second and a third sidewall. The first sidewall faces the fastener, and the second and third sidewalls include inward recessed surfaces and are respectively connected with two side edges of the first sidewall. When the second tube segment is forced to displace relative to the first tube segment, the fastener and the first sidewall push against each other to cause deformation of the cushion part.
1. A child safety seat assembly comprising:
a shell body for defining a support base attachable to a child seat;
a leg frame coupled with the shell body, the leg frame being operable to extend downward from a bottom of the shell body, wherein the leg frame includes a first and a second tube segment attached with each other, the first tube segment being further affixed with a fastener; and
a cushion part affixed in the second tube segment adjacent to the fastener, wherein the cushion part is formed as an integral hollow body including a first, a second and a third sidewall, the first sidewall facing the fastener, and the second and third sidewalls respectively including inward recessed surfaces and being respectively connected with two side edges of the first sidewall;
wherein the fastener and the first sidewall push against each other to cause deformation of the cushion part when the second tube segment and the cushion part are forced to displace in unison relative to the first tube segment and the fastener.
2. The child safety seat assembly according to claim 1 , wherein the second and third sidewalls respectively include openings formed through the inward recessed surfaces.
3. The child safety seat assembly according to claim 2 , wherein the hollow body includes an inner cavity that extends from a first to a second end portion thereof, the openings formed through the inward recessed surfaces respectively communicating with the inner cavity.
4. The child safety seat assembly according to claim 3 , wherein when the second tube segment is forced to displace relative to the first tube segment, the region where the fastener and the first sidewall contact with each other is located at a middle of the hollow body between the first and second end portions.
5. The child safety seat assembly according to claim 1 , wherein when the second tube segment is forced to displace relative to the first tube segment, the region where the fastener and the first sidewall contact with each other is located adjacent to the inward recesses surfaces of the second and third sidewalls.
6. The child safety seat assembly according to claim 1 , wherein the cushion part is made of a metallic material or plastics material.
7. A child safety seat assembly comprising:
a shell body;
a leg frame coupled with the shell body, the leg frame being operable to extend downward from a bottom of the shell body, wherein the leg frame includes a first and a second tube segment attached with each other, the first tube segment being further affixed with a fastener; and
a cushion part affixed in the second tube segment adjacent to the fastener, wherein the cushion part is formed as an integral hollow body having an inner cavity, the hollow body including two opposite end portions, and a first, a second and a third sidewall respectively extending between the two end portions, the first sidewall facing the fastener, and the second and third sidewalls respectively including inward recessed surfaces and being respectively connected with two side edges of the first sidewall;
wherein the fastener and the first sidewall push against each other to cause bending deformation of the first sidewall toward the inner cavity when the second tube segment and the cushion part are forced to displace in unison relative to the first tube segment and the fastener.
8. The child safety seat according to claim 7 , wherein the inner cavity extends from one of the two end portions to the other end portion.
9. The child safety seat according to claim 7 , wherein the second and third sidewalls respectively include openings formed through the inward recessed surfaces.
10. The child safety seat according to claim 9 , wherein the openings formed through the inward recessed surfaces respectively communicate with the inner cavity.
11. The child safety seat according to claim 9 , wherein when the second tube segment is forced to displace relative to the first tube segment, the region where the fastener and the first sidewall contact with each other is located adjacent to the openings formed through the inward recessed surfaces of the second and third sidewalls.
12. The child safety seat according to claim 7 , wherein the cushion part is made of a metallic material or plastics material.
