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 plastic center frame portion; a first wing member comprising a first curved plastic wing frame portion, the first curved plastic wing frame portion providing an off-axis wing frame end portion, 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. A headrest comprising:
-
a headrest body portion; a first head support member pivotally connected to the headrest body portion, the first head support member being pivotable to a first substantially flat position in which the first head support member is substantially parallel to a front face portion of the headrest body portion and pivotable to a rotation stop position at which pivoting of the first head support member is limited to a first acute angle with respect to said headrest body portion, said first head support member being maintained in a plurality of first head support member positions between the first substantially flat position and the first acute angle, said first head support member to pivot if a greater force than a human head leaning against the first head support member is applied; a second head support member pivotally connected to the headrest body portion, the second head support member being pivotable to a second substantially flat position in which the second head support member is substantially parallel to the front face portion of the headrest body portion and pivotable to a second rotation stop position at which pivoting of the first bead support member is limited to a second acute angle with respect to said headrest body portion, said second head support member being maintained in a plurality of second head support member positions between the first substantially flat position and the second acute angle, said second head support member to pivot if the greater force than the human head leaning against the second head support member is applied. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A headrest comprising:
-
a back member, said back member having a plastic back member frame having a plurality of cut out areas; a first wing, said first wing having a first wing frame made of plastic; a second wing, said second wing having a second wing frame made of plastic; a first hinge member, said first hinge member pivotally connecting the first wing to the back member, the first wing being pivotable to a first substantially flat position and pivotable to a first rotation stop position at which pivoting of the first wing is limited to a first acute angle with respect to said back member set by a first forward rotation limiter, said first hinge member having sufficient friction to maintain said first wing in a plurality of first wing positions between the first substantially flat position and the first acute angle, said first wing to pivot if a greater force than a human head leaning against the first wing is applied, said first hinge member having a first metal portion molded over by a first plastic portion of the first wing; a second hinge member, said second hinge member pivotally connecting the second wing to the hack member, the second wing being pivotable to a second substantially flat position and pivotable to a second rotation stop position at which pivoting of the second wing is limited to a second acute angle with respect to said back member sot by a second forward rotation limiter, said second hinge member having sufficient friction to maintain said second wing in a plurality of second wing positions between the second substantially flat position and the second acute angle, said second wing to pivot if a greater force than a human head leaning against the second wing is applied, said second hinge member having a second metal portion molded over by a second plastic portion of the second wing. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40)
