A seat back 28 is mounted to the seat bottom 26 for receiving a back of the user and for supporting the back of the user. Similar to the seat bottom, the seat back 28 includes a frame that is covered by cushioning, which may be foam padding, and a cover.
The chair 20 also includes a pair of armrests 30, 32 that are each mounted to an underside of the seat bottom 26 and extend upward from lateral sides of the seat bottom 26 for receiving and supporting the arms of the user.
As is known in the art, each of the structural features of the chair 20 are adjustable. For example, the height of the seat bottom 26 is adjustable relative to the base 22; a resistance spring force upon the tilt connection between the seat bottom 26 and the base 22 is adjustable; a tilt angle of the seat back 28 relative to the seat bottom 26 is adjustable; and the height of the armrests 30, 32 relative to the seat bottom 26 are adjustable.
The seat back 28 includes a peripheral frame that is padded with cushioning and a cover 34. The cover 34 and underlying cushioning extend around the periphery of the seat back frame, which includes a lower pelvic region, side bolsters, and an upper shoulder and headrest region. The back rest 28 also includes a central fabric cover 36 mounted within the peripheral cover 34 and supported by the frame of the seat back 28. In one embodiment of the invention, the cover 36 is a mesh fabric that is mounted in tension to support the back of the user.
The seat back 28 includes a massage unit 38 that is mounted to a rear side of the seat back 28 and is connected to the frame. The massage unit 38 imparts a massage effect to the central cover 36 for massaging the back and shoulders of the user. The massage unit 38 is selectively detachable so that the user can utilize the chair 20 as a conventional office chair with or without the massage unit 38, or so that the user can utilize the chair 20 in combination with the massage unit 38 for seating the user and imparting the massage effect upon the back of the user. By providing the seat back 28 with a peripheral frame, and the central cover 36, the massage unit 38 can be selectively attached to the seat back 28 for providing the massage effect, or detached for providing a conventional seating configuration with the central cover 36 in tension for providing rear support. Alternatively, the massage unit 38 may be replaced with a structural blank, such as foam or padding to support the cover 36 from the rear.
Alternatively, multiple massage units 38 may be employed, each having a varying massage effect such that the user can remove one massage unit 38 and replace it with another massage unit 38. In addition, the detachability of the massage unit 38 provides ease and servicing and maintenance of the massage unit 38.
One such suitable massage unit is disclosed in Ferber et al. U.S. Patent Application Publ. 2007/0060851 A1, which published on Mar. 15, 2007 and is incorporated in its entirety by reference herein. The massage mechanism may be imparted directly to the underside of the central cover 36 so that the rollers provide rolling and kneading massage effects upon the back of the user.
Other known suitable massage units 38 can be utilized in combination with the chair 20 in accordance with the present invention such as rotary kneading massage units, hemispherical roller massage units, percussion (tapping) massage units, and any other suitable massage unit that can be contained within the massage unit such as massage unit 38 and installed into the seat back 28.
