Claim 10

Dependent Claim 25 words

The child seat of claim 4 wherein at least a portion of said headrest is disposed within said recess when in a lowered stowage position.

Claim 11

Dependent Claim 120 words

A child seat integrated into a vehicle seat and adapted to be moved from a stowed position to a deployed position by lowering a seat member and elevating a headrest, thereby exposing a backrest and safety belt restrain system, said child seat having latching means for retaining said seat member in said stowed position, said latching means comprising a pliable member extending from said seat member and retaining means affixed to a free end of said pliable member for operatively engaging a portion of said backrest when said seat member is in said stowed position such that said seat member is maintained in a held relationship with respect to said backrest when said seat member is in said stowed position.

Claim 12

Dependent Claim 120 words

A child seat integrated into a vehicle seat and adapted to be moved from a stowed position to a deployed position by lowering a seat member and elevating a headrest, thereby exposing a backrest and safety belt restrain system, said child seat having latching means for retaining said seat member in said stowed position, said latching means comprising a pliable member extending from said seat member and retaining means affixed to a free end of said pliable member for operatively engaging a portion of said backrest when said seat member is in said stowed position such that said seat member is maintained in a held relationship with respect to said backrest when said seat member is in said stowed position.

Claim 13

Dependent Claim 28 words

The child seat of claim 9 wherein said pliable member provides a protective cover for said vehicle seat when said seat member is in a lowered operative position.

Claim 14

Dependent Claim 76 words

The child seat of claim 9 wherein said retaining means comprises a plurality of fasteners provided on the distal free end of said pliable member which are engagable with a corresponding plurality of fasteners retainers located on an upper portion of said backrest, whereby when said seat member is in said stowed position said pliable member extends upwardly from said seat member along said backrest and is removably affixed to said upper end of said backrest.

Claim 15

Dependent Claim 52 words

The child seat of claim 11 wherein said upper end of said backrest pivotally supports a headrest such that when said headrest is pivoted into a lowered stowed position, said headrest operatively engages at least a portion of said pliable member, thereby retaining said pliable member between said headrest and said backrest.

Claim 16

Dependent Claim 54 words

The child seat of claim 12 wherein said fastener retainers vertically extend from a portion of said backrest such that when said seat member is in said stowed position and said fastener retainers are engaged by said fasteners, tension upon said pliable member creates a shear load between said fasteners and said fastener retainers.

Claim 17

Dependent Claim 202 words

In a child seat integrated into a backrest of a vehicle seat and adapted to be moved from a stowed position concealed within the backrest to a deployed position by elevating a headrest and lowering a seat member for exposing a child seat backrest and a safety belt restraint system, the improvement comprising: first energy absorbing means disposed within the headrest for absorbing energy dissipated when a child seat occupant's head operatively engages said first energy absorbing means; second energy absorbing means affixed to an upper portion of the child seat backrest, said second energy absorbing means having a laterally extending cover member and a pair of end portions extending from opposite ends of said laterally extending cover member, said second energy absorbing means provided for absorbing energy dissipated when the seat occupant's torso operatively engages said second energy absorbing means; and a pliable member extending from a portion of the seat member, said pliable member having retaining means affixed thereto for operatively engaging a portion of the child seat backrest when the seat member is in the stowed position such that the seat member is maintained in a fixed position with respect to the backrest when said retaining means are engaged.

Claim 18

Dependent Claim 202 words
