ABSTRACT:
A support for maintaining the head in an upright position while the seat-occupant is seated in a reclining seat. One part of the support is a forehead-engagement means to resist forward movement of the head. Forehead pressure against this means is transmitted by connecting means to a back-plate positioned between the back of the seat-occupant and the back-rest of the seat. With the seat-back-rest partially backward-inclined, and the forehead inclined sightly forward to rest forward against the forehead-engagement means, there is a tendency for the back-plate to rotate forward at the top and backward at the bottom. At the top, it's resisted by the seat-occupant's back, resting backward against the back-plate; at the bottom, this rotational tendency is resisted by the seat-back-rest. The back-plate, thus sandwiched between the seat-occupant and the seat, maintains the forehead-engagement means in position to resist the forward-pressure of the resting forehead, so that the forehead is prevented from falling forward and downward toward the chest; in other words, the head is thus supported.
Ancillary support means can be added to supplement the basic head-support above-described. Thus, for instance, there may be lateral-support means engaging the shoulders as part of the connecting means or back-plate, to resist lateral movement of the sleeping or resting head in the event that the seat-occupant (for example) is in transit aboard a vehicle which sways from side to side thus tossing the head left and right.
All versions of this head-support depend upon the basic principle of preventing forward-falling of the forehead by transmitting this forward pressure via the connecting means to the back-plate sandwiched between the seat-occupant's back and the seat-back-rest.
