Child safety seat with energy absorbing elements
Child safety seats including energy absorbing elements in accordance with embodiments of the invention are disclosed. In a variety of embodiments, a child safety seat includes a seat body comprising an outer surface and at least one energy absorber coupled to the outer surface, the energy absorber including an outwardly facing surface facing away from the outer surface of the seat body, an inwardly facing surface facing towards the outer surface of the seat body, and at least one energy absorbing element located between the outwardly facing surface and the inwardly facing surface, wherein the energy absorber absorbs energy in response to an impact.
1. A child safety seat, comprising:
a seat body comprising an outer surface; and
at least one energy absorber coupled to the outer surface, the energy absorber comprising:
an outwardly facing surface facing away from the outer surface of the seat body;
an inwardly facing surface facing towards the outer surface of the seat body; and
at least one energy absorbing element located between the outwardly facing surface and the inwardly facing surface;
wherein the energy absorber absorbs energy in response to an impact;
wherein each energy absorbing element extends a respective depth towards the inwardly facing surface;
wherein a first energy absorbing element extends a first depth; and
wherein a second energy absorbing portion extends a second depth different than the first depth.
2. The child safety seat of claim 1 , wherein the seat body comprises an inner surface defining an area where an occupant can be seated.
3. The child safety seat of claim 1 , wherein the energy absorber absorb energy via plastically deforming, cushioning, crushing, rupturing, deflating or bursting.
4. The child safety seat of claim 1 , wherein the energy absorber comprises an aperture allowing a fluid to be released from the energy absorber in response to the impact.
5. The child safety seat of claim 1 , wherein each energy absorbing element has a first portion having first width adjacent a non-recessed portion of the outwardly facing surface and second portion having a second width, wherein the first width is greater than or equal to the second width.
6. The child safety seat of claim 5 , wherein each energy absorbing portion is configured such that the impact causes the second width of at least one energy absorbing portion to increase.
7. The child safety seat of claim 6 , wherein the second width increases to be greater than the first width in response to the impact.
8. The child safety seat of claim 1 , wherein at least one of the at least one energy absorbing element has an elongate shape.
9. The child safety seat of claim 1 , wherein at least one of the at least one energy absorbing element has a square shape.
10. The child safety seat of claim 1 , wherein the energy absorber is constructed at least in part with low density polyethylene.
11. The child safety seat of claim 1 , further comprising a gap between the at least one energy absorbing element and the outwardly facing surface.
12. The child safety seat of claim 1 , wherein the at least one energy absorbing element is in contact with the outwardly facing surface.
13. The child safety seat of claim 1 , wherein the energy absorber is constructed at least in part with plastic.
14. A child safety seat, comprising:
a seat body comprising an outer surface; and
at least one energy absorber coupled to the outer surface, the energy absorber comprising:
an outwardly facing surface facing away from the outer surface of the seat body;
an inwardly facing surface facing towards the outer surface of the seat body; and
at least one energy absorbing element located between the outwardly facing surface and the inwardly facing surface;
wherein the at least one energy absorber plastically deforms in response to an impact;
wherein each energy absorbing element extends a respective depth towards the inwardly facing surface;
wherein a first energy absorbing element extends a first depth; and
wherein a second energy absorbing portion extends a second depth different than the first depth.
15. The child safety seat of claim 14 , wherein the at least one energy absorbing element forms an array of energy absorbing elements that collectively deform in response to the impact.
16. The child safety seat of claim 14 , wherein:
the child safety seat is mounted in a vehicle; and
at least one energy absorber of the at least one energy absorber plastically deforms in response to the impact to the vehicle.
17. The child safety seat of claim 16 , wherein the impact to the vehicle comprises a side impact.
18. The child safety seat of claim 14 , wherein the outwardly facing surface and the inwardly facing surface form a shell of the energy absorber.
19. The child safety seat of claim 18 , wherein the shell is formed at least in part by a polymeric material.
