Abstract: Cushions include a chassis core having a rigid or semi-rigid base sheet; and a plurality of paired flat springs coupled to the rigid or semi-rigid base sheet, wherein each paired flat spring comprises a lower flat spring including a first terminal end, a second terminal end, and a flexible arcuate member extending from the first terminal end to the second terminal end, and an upper flat spring including a first terminal end, a second terminal end, and a flexible arcuate member extending from the first terminal end to the second terminal end, wherein the first and second terminal ends of the upper flat spring are fixedly attached to respective first and second terminal ends of the lower flat spring such that the upper flat spring is inverted relative to the lower flat spring. Also disclosed are processes for manufacturing the core chassis.

Abstract: Stimulation actuators that exert any desired movements on the underspringing arrangement. The underspringing arrangement has lifting members (11) that are mounted elastically by means of elastic elements (14). The elastic elements (14) are arranged such that at least a main direction of work extends at an angle with respect to the direction of the movement of the lifting member. In this way, the lifting member (11) can have a particularly low overall height. The supporting surface of the underspringing arrangement can be moved up and down by the lifting member (11) and the elastic element (14), thereby permitting an individual stimulation and movement of a person lying on the mattress.

Abstract: A lying surface for a bed, especially for a healthcare and/or hospital bed, comprises support elements (22) and at least one electro-mechanic lifting unit (20) for lifting and lowering one of the support elements (22) relative to a bearing element (62) of the support element (22). The at least one lifting unit (20) comprises a housing (24) with an electromotor (32) having a drive shaft (34), a transmission (38) and a lifting member (50) supported at the bearing element (62) of said one support element (22). The lifting member (50) is adapted to be rotated by the transmission (38) and to be moved both up and down during a rotary movement of 360°.

Abstract: An inflatable cervical cushion for providing support to the cervical spine and surrounding cervical musculature of the wearer while seated. The present invention is for an inflatable cervical cushion which adjustably reinforces the neck to support the cervical spine in a proper lordotic position, alleviating neck pain caused by improper posture and fatigue. The cushion encircles the wearer's neck and rests on the wearer's shoulders, and contains a compartment with an inflatable cushion centrally located in the back of the cushion. The inflatable cushion is of a rectangular or oval design which is positioned horizontally in the back of the neck such that the thicker center portion of the cushion supports the cervical spine and the thinner end portions support the surrounding musculature. In addition, there is a vertical extension from the top of the cushion which supports the base of the skull, or occiput, thereby supporting the skull at the same time of supporting the cervical spine.

Abstract: A bed has a frame and a mattress support. The mattress support is suspended from the bed frame by a plurality of elastic supports. The mattress support can move in a downward direction when weight is applied to the mattress support.

Abstract: A pendulum frame (2) is suspended on a fixed stand (1) by means of four pendulums (16). The amplitude of each of the pendulums (16, 17) is limited by a plate (24) provided with an orifice (23). The plates (24) carry locking projections (28), into which detent pawls (26), arranged on the pendulum frame (2) can engage. When only one of these detent pawls (26) is in the locking position, the bedding furniture can swing about this detent pawl which functions as a pivot pin. When two detent pawls (26) located behind one another in the longitudinal direction of the bedding furniture are locked, the pendulum frame (2) is blocked and is held outside its mid-position on one side. A free-swinging mid-position, four pendulum positions locked at one point and two fixing positions locked off-center are therefore available for each piece of bedding furniture.The bedding furniture can be adapted to meet individual sleeping requirements and is also characterized in that bed care becomes considerably easier.

Abstract: A suspension system for furniture and furniture incorporating such system whereby forces applied to the furniture are effectively dissipated or cushioned to afford comfortable conditions for a user of the furniture.
