The lumbar support mechanism and an adjustable bed therewith. The lumbar support mechanism includes a lumbar support member; first, second, third and fourth support legs; a linkage member; and first and second lumbar support brackets attached onto the adjustable bed. Upper ends of the first and second support legs are pivotally connected to the lumbar support member, and lower ends of the first and second support legs are pivotally connected to the linkage member, respectively. Upper ends of the third and fourth support legs are pivotally connected to the first and second support legs, respectively, and lower ends of the third and fourth support legs are pivotally connected to the first and second lumbar support brackets, respectively. As such, a distance between the lumbar support member and the linkage member is changeable between minimal and maximal distances when the linkage member moves between first and second positions.

Disclosed are a device for the opening of an adjustable sofa without pausing and a mechanical stretching device thereof. The device for the opening of an adjustable sofa consists of a leg drive connector (4), a first limit push connector (3), an expansion front swing limit (1), a second limit push connector (10), a back swing limit (6), a transmission connector (9), a third limit push connector (8), a limit push slide groove block (7) and a folding front swing limit (11). The leg drive connector (4) is rotatably connected to the first limit push connector (3). The transmission connector (9) is rotatably connected to the second limit push connector (10). The second limit push connector (10) is rotatably connected to the first limit push connector (3) and the third limit push connector (8). The back swing limit (6) is fixed on the third limit push connector (8) and located in a limit push slide groove (15). The expansion front swing limit (1) is fixed on the second limit push connector (10). The expansion front swing limit (1) cooperates with a front swing connector (12) and the back swing limit (6) cooperates with a back swing connector (5).

The invention concerns an adjustable bed (10) having zero wall clearance and zero gravity functionality. The bed comprises a frame (20) and an adjustable mattress support platform (11) having a plurality of articulated support sections (12, 16, 18) pivotally mounted with respect to one another for relative angular adjustment, and actuator means (52) for effecting coordinated movement of the support sections to reconfigure the bed, between a flat lowered configuration and a raised configuration for supporting an occupant in a zero gravity recumbent position. The actuator means comprises a single actuator, preferably a single linear actuator.

A multi-factor authentication method and system is provided such that a push notification during an authentication process is only received if a mobile device and user are authenticated prior to receiving the push notification. Either the mobile device itself or a second device sending the push notification may be programmed to either reject or not forward the authentication request. Additionally, using the method of the present invention, enhanced security is provided by requiring the location of the mobile device and the second device to be approximately in the same geographical location.

An articulating bed incorporates a support frame with a head end, a foot end and having side frame members. A carriage having a seat support is carried by the frame, mounted with wheels engaging the side frame members to translate from a first position through a range progressing toward the head end to a fully translated position. An upper body support is rotatably connected to the carriage and carries a mattress support. At least one telescoping rotation strut is attached at a first end and rotates through an axle pivotally attached to the side frame members. The telescoping rotation strut engages at a second end the upper body support. At least one fixed length rotation arm is carried at a first end by a rotating tube and pivotally attaches to the upper body support at a second end. The rotating tube is mounted on wheels constrained in a track and translates laterally in the track to contact a track end proximate the head end of the frame at a termination of a first range of motion. The telescoping strut approaches a vertical orientation and transfers reaction forces resulting from translation of the carriage to the fixed length rotation arm, whereupon the telescoping rotations struts extend.
