Headrest for chair with soft backrest

Claim 2

A headrest device particularly adapted for removable installation upon a non-rigid backrest of a chair or wheelchair, comprising a first elongate member of generally U-shaped configuration, a pillow-like head-contacting member mounted upon the upper end of said first member, a second generally U-shaped member residing in a plane generally parallel to the plane of said first member, means provided on said second member for slidable attachment to portions of said first member, with said second member being slidable in order that a height adjustment for said head-contacting member can be achieved, a major portion of said second member being spaced close to said first member so as to define a relatively narrow slot between said members, into which slot the fabric backrest portion of a chair or wheelchair can be received, with the length of said first member and said second member being such that they extend down along opposite sides of a backrest portion of the chair or wheelchair for a sufficient distance as to provide a stable mounting for said head-contacting member, said first and second members each having a comparatively wide lateral spacing for stability reasons, and said first member possessing a slight degree of out-of-plane curvature in order to essentially coincide with the natural curvature of the spine of the occupant of the chair or wheelchair, said head-contacting member being adjustably mounted upon said first member, so that adjustments of said head-contacting member in a direction substantially perpendicualr to the plane of said first member can be accomplished.

Claim 3

The headrest device as defined in claim 1 in which finger-operated locking means are provided in the said means for slidable attachment of said second member to said first member, such that undesired movement of said head-contacting member away from a selected position can be prevented.

Claim 4

A headrest device particularly adapted for removable installation upon a non-rigid backrest of a chair or wheelchair, comprising a first elongate member of generally U-shaped configuration, a pillow-like head-contacting member mounted upon the upper ends of the arms of said first U-shaped member, a second elongate generally U-shaped member residing in a plane parallel to the plane of said first member, means provided at the top of said second member for slidable attachment to the arms of said first member, with said second member being slidable along the arms of said first member in order that a height adjustment for said head-contacting member can be achieved, the major portion of said second member being spaced close to said first member so as to define a narrow slot between said members, into which slot the fabric backrest portion of a chair or wheelchair can be received, with the length of the arms of said first member and said second member being such that they extend down along the backrest portion of the chair or wheelchair for a sufficient distance as to provide a stable mounting for said head-contacting member, said head-contacting member being adjustably mounted upon the arms of said first member so that adjustments of said head-contacting member in a direction substantially perpendicular to the plane of said first member can be accomplished, the arms of said first elongate member possessing a slight degree of curvature such that the lower portion of said first elongate member has moved slightly away from a planar relationship with said second member, such curvature adding to the comfort of an occupant of the chair or wheelchair.

Claim 5

A headrest device particularly adapted for removable installation upon a non-rigid backrest of a chair or wheelchair, comprising a first elongate member of generally U-shaped configuration, a pillow-like head-contacting member mounted upon the upper ends of the arms of said first U-shaped member, a second elongate generally U-shaped member residing in a plane parallel to the plane of said first member, means provided at the top of said second member for slidable attachment to the arms of said first member, with said second member being slidable along the arms of said first member in order that a height adjustment for said head-contacting member can be achieved, the major portion of said second member being spaced close to said first member so as to define a narrow slot between said members, into which slot the fabric backrest portion of a chair or wheelchair can be received, with the length of the arms of said first member and said second member being such that they extend down along the backrest portion of the chair or wheelchair for a sufficient distance as to provide a stable mounting for said head-contacting member, said head-contacting member being adjustably mounted upon the arms of said first member so that adjustments of said head-contacting member in a direction substantially perpendicular to the plane of said first member can be accomplished, the arms of said first elongate member possessing a slight degree of curvature such that the lower portion of said first elongate member has moved slightly away from a planar relationship with said second member, such curvature adding to the comfort of an occupant of the chair or wheelchair.

Claim 6

The headrest device as defined in claim 3 in which finger-operated locking means are provided in the means slidably attaching said second member to the arms of said first member, such that undesired movement of said head-contacting member away from a selected position can be prevented.
