## Abstract

A side impact protection device for a child car seat comprised of an energy absorbing element and an energy dispersing element.

## Claims

### Claim 1

A child car seat comprising:
a headrest portion;
an energy absorbing structure incorporated into the headrest portion, the energy absorbing structure including at least two separate energy absorbing elements and an energy dispersing element and being mounted inside a housing mounted for sliding movement with respect to the headrest portion;
wherein the energy absorbing elements are separated by the energy dispersing element, the energy dispersing element is comprised of a plate and a protrusion, and at least one of the energy absorbing elements includes a relief portion to receive the protrusion.

### Claim 2

The child car seat of clam 1 wherein the energy absorbing elements are comprised of an open cell foam, a closed cell foam, or expanded polystyrene.

### Claim 3 (depends on 1)

The child car seat of claim 1 wherein the energy absorbing structure includes a housing for housing the energy absorbing elements and the energy dispersing element.

### Claim 4 (depends on 3)

The child car seat of claim 3 wherein the housing includes a body portion and a flange portion and the flange portion is shaped to engage a portion of a cap positioned thereover to prevent outward movement thereof.

### Claim 5

The child car seat of clam 1 wherein the headrest portion includes at least one wing portion and the energy absorbing structure is mounted on the at least one wing portion.

### Claim 6 (depends on 1)

The child car seat of claim 1 wherein the energy dispersing element is comprised of at least one crush element.
