A recently granted patent (Publication Number: US11672348B2) describes a furniture assembly with a unique lumbar adjustment assembly and a built-in massaging unit. The assembly includes a seat bottom and a seatback with a seatback frame. The lumbar adjustment assembly is mounted to the seatback frame and consists of a rail, a threaded rod, two slider blocks, a lumbar pad, and a series of links connecting the lumbar pad to the slider blocks. The threaded rod has two sections with opposite thread directions, and each slider block engages one of the sections. The massaging unit is mounted to the lumbar pad.
The patent also describes an adjustment assembly for the furniture assembly, which includes a motor assembly, a rail, a threaded rod, two slider blocks, a series of links, a support member, and a massaging unit. The support member is attached to the links and the massaging unit is mounted to the support member. The assembly allows for the movement of the support member in a direction perpendicular to the movement of the slider blocks along the rail. The motor assembly drives the threaded rod, which in turn moves the slider blocks and the support member.
The furniture assembly also includes a seat bottom, a seatback with a seatback frame, and a lumbar adjustment assembly. The lumbar adjustment assembly consists of a lumbar pad, a series of links, and a motor assembly. The motor assembly drives the links to move the lumbar pad relative to the seatback frame, allowing it to push against the upholstery of the seatback. The lumbar pad also has a built-in massaging unit that moves with the pad.
Overall, this patent describes a furniture assembly with a unique lumbar adjustment assembly and a built-in massaging unit. The assembly allows for customizable lumbar support and provides a massaging function for added comfort. The design includes various components such as slider blocks, threaded rods, links, and motor assemblies to enable the desired movements and functions. This innovation could potentially enhance the ergonomic features and user experience of furniture, particularly chairs and seats.
