Abstract
A headrest assembly for a chair or sofa includes a fixed rear section, and a front section adapted to slide upwardly and forwardly to an inclined orientation with respect to the rear section. Movement of the front section is controlled by a linear actuator, which is connected via a switch to a source of power such as a battery.
Description
- This application claims priority on U.S. Provisional Application 60/818,548 filed Jul. 6, 2006.
- 1. Field of the Invention
- This invention relates to an adjustable headrest assembly.
- While the headrest assembly was designed primarily for use on a chair or sofa, it will be appreciated that the assembly can be used in an automotive or other vehicle.
- 2. Description of Related Art
- There is a considerable volume of patent literature relating to adjustable headrests. In this connection, reference is made to U.S. Pat. Nos. 4,370,898, which issued to K. Maruyama on Feb. 1, 1983, 4,640,549, which issued to M. Yokota on Feb. 3, 1987, 4,668,014, which issued to B. Boisset on May 26, 1987, 4,674,797, which issued to T. Tateyama on Jun. 23, 1987, 5,236,246, which issued to D. J. Harrell on Aug. 17, 1993, 5,238,295, which issued to D. J. Harrell on Aug. 24, 1993, 5,346,283, which issued to U. Steininger et al on Sep. 13, 1994 and 6,471,296, which issued to M. A. Lance on Oct. 29, 2002.
- It will be noted that most of the apparatuses disclosed by the above listed patents are somewhat complicated and consequently expensive to manufacture.
- The present invention provides a relatively simple headrest assembly which includes a few, easily assembled elements.
- Accordingly, the invention relates to a headrest assembly comprising a rear section for mounting in a fixed position on a chair or sofa; a front section pivotally and slidably mounted on said front section for movement between various inclined positions with respect to said rear section; and an actuator for moving said front section with respect to said rear section between the various inclined positions.
- The invention is described below with reference to the accompanying drawings, wherein:
-
FIG. 1 is a isometric view of a headrest assembly in accordance with the present invention in a first position; -
FIG. 2 is an isometric view of the headrest assembly ofFIG. 1 in a second position; -
FIG. 3 is an isometric view of a rear section of the headrest assembly ofFIGS. 1 and 2 ; and -
FIG. 4 is a cross-sectional view of the headrest assembly ofFIGS. 1 to 3 . - With reference to the drawings, the principal elements of the headrest assembly of the present invention include a
rear section 1, afront section 2 and alinear actuator 3. Therear section 1 of the assembly includes arectangular back plate 4 for mounting in a fixed position on a chair or sofa back (not shown). The rear section can be mounted on the rear of a padded headrest (not shown). It will be appreciated that theplate 4 could also define the back of a headrest. A pair of generally inverted L-shaped end plates 5 are integral with theback plate 4 and extend forwardly therefrom. Eachend plate 5 includes upper andlower slots pins upper slots 7 are inclined upwardly and outwardly, and thelower slots 8 are vertical. Thepins end walls 13 of thefront section 2 of the headrest assembly. Theend walls 13 are integral with arectangular front wall 14. Thus, thefront section 2 of the assembly is generally C-shaped when viewed from above or below, and theend walls 13 overlap theend plates 5 of therear section 1. While they are not shown, it will be appreciated that padding and a cover would be added to the whole assembly or at least to theend walls 13 and thefront wall 14 of the front section. Accordion pleats in the cover would permit movement of the front section relative to the rear section. - The
linear actuator 3, which is a piece of off-the-shelf hardware, includes a direct currentelectric motor 16 connected through switches to a source of electrical power such as a battery (not shown). The switches can be mounted for manual operation in or on the arm of a chair or sofa. Themotor 16 is connected to a spindle (not shown) in thehousing 17 by atransmission 18. Acoupling 20 on the bottom, transmission end of the housing is pivotally connected to the center of the bottom end of the rearsection back plate 4 by aclevis 21. Areciprocating shaft 22 extending out of the top end of thehousing 17 is pivotally connected to the center of the top end of thefront wall 14 of thesecond section 2 by aclevis 23. A suitable linear actuator is available from Jaeger Industrial Co. Ltd., Taipei, Taiwan, R.O.C. - In operation, with the
shaft 22 of thelinear actuator 3 retracted (FIG. 3 ), thebottom wall 14 of thefront section 2 defines a small acute angle with theback plate 4 of the rear section 1 (FIG. 1 ). When theshaft 22 of the linear actuator is extended, thepins 9 slide upwardly and outwardly in theslots 7 and thepins 10 side upwardly inslots 8 so that thefront wall 14 defines a larger acute angle with respect to theplate 4, i.e. thefront section 2 becomes more inclined with respect to therear section 1. Thus, by connecting thelinear actuator 3 to a forward and reverse switch (not shown), which is in turn connected to a source of electrical power, the inclination or tilt of the front section of the headrest assembly can be changed.
