1. A head support assembly comprising:
- a back member comprising a frame portion;
a first wing member comprising a first deformable plastic wing frame portion, the first deformable plastic wing frame comprising a first buckling portion adapted to facilitate buckling when subject to a compressive load, the first wing member being pivotally interconnected to the back member, the first wing member being pivotable from a flat position substantially planar with the back member inwardly to a select limited angle which is an acute angle;
a second wing member comprising a second deformable plastic wing frame portion, the second deformable plastic wing frame portion comprising a second buckling portion adapted to facilitate buckling when subject to the compressive load, the second wing member being pivotally interconnected to the back member, the second wing member being pivotable from a flat position substantially planar with the back member inwardly to a select limited angle which is the acute angle, the second wing member being pivotable independently from the first wing member.

Abstract
A headrest with pivotable side support members and safety features. A head support assembly according to one embodiment includes a first wing member including a deformable plastic wing frame portion. The head support assembly also includes a center member that includes a plastic center frame portion to which the first wing member is pivotably coupled. The forward pivoting of the first wing member is limited an acute angle.

13. A headrest comprising:
-
a center member comprising a semi-rigid center frame portion;
a first wing member comprising a first deformable plastic wing frame portion, the first deformable plastic wing frame portion to plastically yield but not permanently deform, the first wing member being pivotally interconnected to the center member and being unassistedly maintained in a plurality of in-use positions between a flat position substantially planar with the center member and a rotation limit position;
a first wing member rotation stop to prevent pivoting of the first wing member beyond the rotation limit position at which the first wing member has only been pivoted to an acute angle with regard to the center member. - View Dependent Claims (14, 15, 16, 17)

18. An assembly comprising:
-
a head support center portion comprising a frame;
a first lateral support member comprising a safety enhanced wing that includes a portion to plastically deform in response to a compressive load, said first lateral support member being pivotally coupled to the head support center portion and also being padded, said first lateral support member providing sufficient head support to support a force of a human head leaning against the first lateral support member in a plurality of first lateral support member positions between a first substantially flat position and a first acute angle, said first lateral support member to pivot if a greater force than the force of the human head leaning against the first lateral support member is applied;
a rotation stop mechanism to limit the first lateral support member to pivoting to the first acute angle. - View Dependent Claims (19, 20, 21, 22)
