Abstract

Abstract A child safety seat including a seat bottom and seat back first and second resilient side elements carried on laterally-opposed sides of the seat back, and including walls defining an enclosed chamber. The walls have sufficient rigidity to maintain a nominal shape and are deformable in response to a predetermined minimum impact.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 170 words
A child safety seat, comprising: (a) a seat frame including a seat bottom, a seat back and a headrest; (b) first and second elongate, resilient impact-resisting side elements positioned outboard of respective laterally-opposed sides of the seat back and headrest, the first and second impact-resisting side elements extending from proximate respective laterally-opposed sides of the headrest to a position proximate a seating surface of the seat bottom, and comprising walls defining a unitary chamber having an interior volume; (c) an air flow opening in the walls of the chamber for permitting air flow communication between the interior volume of the chamber and surrounding ambient air; (d) the resilient side elements having a wall thickness and construction permitting deformation of the side elements at a controlled rate in response to a side impact; and (e) wherein each side element is mounted to the seat back with at least one mechanical fastener, and further wherein the at least one mechanical fastener is mounted to the seat back through the air flow opening.
Claim 2
Dependent Claim 170 words
A child safety seat, comprising: (a) a seat frame including a seat bottom, a seat back and a headrest; (b) first and second elongate, resilient impact-resisting side elements positioned outboard of respective laterally-opposed sides of the seat back and headrest, the first and second impact-resisting side elements extending from proximate respective laterally-opposed sides of the headrest to a position proximate a seating surface of the seat bottom, and comprising walls defining a unitary chamber having an interior volume; (c) an air flow opening in the walls of the chamber for permitting air flow communication between the interior volume of the chamber and surrounding ambient air; (d) the resilient side elements having a wall thickness and construction permitting deformation of the side elements at a controlled rate in response to a side impact; and (e) wherein each side element is mounted to the seat back with at least one mechanical fastener, and further wherein the at least one mechanical fastener is mounted to the seat back through the air flow opening.
Claim 3
Dependent Claim 15 words
The child safety seat according to claim 1 , wherein the side elements are blow-molded.
Claim 4
Dependent Claim 35 words
The child safety seat according to claim 2 , wherein the walls are formed of a blow-moldable material selected from the group consisting of polypropylene, ethylene vinyl acetate, low or high density polyethylene and polystyrene.
Claim 5
Dependent Claim 26 words
The child safety seat according to claim 1 , wherein the side elements are shaped to generally conform to adjacent side contours of the seat back.
Claim 6
Dependent Claim 24 words
The child safety seat according to claim 1 , wherein the walls have a thickness of between about 0.070 inches and about 0.090 inches.
Claim 7
Dependent Claim 193 words
A child safety seat, comprising: A child safety seat, comprising: (a) a base to which is mounted a seat having an integrally-formed seat bottom, a seat back, and a headrest; (b) first and second elongate, resilient impact-resisting side elements positioned outboard of respective laterally-opposed sides of the seat back, each of the first and second elongate, resilient impact-resisting side elements extending from proximate respective laterally-opposed sides of the headrest to a position proximate a seating surface of the seat bottom and comprising walls defining an enclosed air chamber, the walls having sufficient rigidity to maintain a nominal shape and deformable in response to a predetermined minimum impact; (c) an air flow opening in the walls of the chamber adapted to allow air flow communication between the chamber and surrounding ambient air at a restricted rate for allowing a controlled release of air from the chamber in response to a deforming impact against the side element, and (d) wherein each side element is mounted to the seat back with at least one mechanical fastener, and further wherein the at least one mechanical fastener is mounted to the seat back through the air flow opening.
Claim 8
Dependent Claim 193 words
A child safety seat, comprising: A child safety seat, comprising: (a) a base to which is mounted a seat having an integrally-formed seat bottom, a seat back, and a headrest; (b) first and second elongate, resilient impact-resisting side elements positioned outboard of respective laterally-opposed sides of the seat back, each of the first and second elongate, resilient impact-resisting side elements extending from proximate respective laterally-opposed sides of the headrest to a position proximate a seating surface of the seat bottom and comprising walls defining an enclosed air chamber, the walls having sufficient rigidity to maintain a nominal shape and deformable in response to a predetermined minimum impact; (c) an air flow opening in the walls of the chamber adapted to allow air flow communication between the chamber and surrounding ambient air at a restricted rate for allowing a controlled release of air from the chamber in response to a deforming impact against the side element, and (d) wherein each side element is mounted to the seat back with at least one mechanical fastener, and further wherein the at least one mechanical fastener is mounted to the seat back through the air flow opening.
Claim 9
Dependent Claim 24 words
The child safety seat according to claim 6 , wherein the walls have a thickness of between about 0.070 inches and about 0.090 inches.
Claim 10
Dependent Claim 35 words
The child safety seat according to claim 6 , wherein a pressurized gas is contained within the chamber for providing controlled resistance to deformation of the side elements in response to a predetermined minimum impact.
Claim 11
Dependent Claim 31 words
The child safety seat according to claim 6 , wherein the chamber contains a supplemental impact material selected from the group consisting of polyethelyne or polystyrene beads, fibers, gels, or liquids.
Claim 12
Dependent Claim 18 words
The child safety seat according to claim 6 , wherein the chamber contains a compressible open-cell foam material.
Claim 13
Dependent Claim 35 words
The child safety seat according to claim 6 , wherein the walls are formed of a blow-moldable material selected from the group consisting of polypropylene, ethylene vinyl acetate, low or high density polyethylene and polystyrene.
Claim 14
Dependent Claim 26 words
The child safety seat according to claim 6 , wherein the side elements are shaped to generally conform to adjacent side contours of the seat back.
Claim 15
Dependent Claim 15 words
The child safety seat according to claim 6 , wherein the side elements are blow-molded.
