A bed apparatus capable of automatically adjusting a bed surface based on a sleeping position is disclosed. The bed apparatus includes a multi-layer bed body including an upper layer and a lower layer, material of the upper layer being softer than the material of lower layer; a shoulder airbag fixedly embedded in the upper layer and supported by the lower layer; a waist airbag movably disposed on the upper layer; a sleeping position sensing unit generating a sensing signal in response to the sleeping position of a user; a control box receiving the sensing signal, and determining the sleeping position of the user based on the sensing signal, and controlling the shoulder airbag or the waist airbag to inflate or deflate, responsively.

The self-adjustable backrest device supplements a seat surface such that said seat surface is a previously existing one and what is covered by the object of this invention adds a backrest or improves the existing one, for which purpose it comprises a mobile plate on which the user rests, wherein said plate swivels on a horizontal shaft that passes through a first set of hubs connected to the plate, that shaft being associated with a second set of hubs connected to a support that may be the backrest itself of the chair or easy chair on which the self-adjustable backrest is going to be used, in which case it will be referred to as pre-existing backrest, or it may be a fixed backrest which forms part of the device, in which case it will be referred to as backrest of the device. The device may include fixing elements to prevent its movement, such as legs, pegs, or a flap.

The present invention relates to a chair which includes a subframe, a seat element, a back element, a spring mechanism and an adjustment device, wherein the spring mechanism includes a leaf spring which is clamped on one side in the subframe and a support which is movable on a track between the leaf spring and the subframe and wherein the adjustment device includes an adjustment member and a transmission mechanism. In this connection, a movement of the adjustment member is translated into a movement of the support at a transmission ratio of between 1:0.5 and 1:4.

A method and system for using in a two-modality apparatus. The two-modality apparatus comprises a couch with a table top, a first modality unit and a second modality unit. A second image of a target portion of an object when the table top is at a second working position of the second modality unit may be acquired. A second sag of the table top at a second measurement point of the table top according to the second image may be determined based on the image. A difference between a first sag of the table top at a first measurement point of the table top and the second sag may be estimated based on the second sag and standard data. The standard data provides a relationship relating to a sag of the table top positioned between the first modality unit and second modality unit.

An arrangement having at least one resting unit (B; Hyx) each having a lying/sitting surface (B1) and an actuator (A; A1 . . . ), configured to act on the lying/sitting surface, to adjust a height and/or firmness profile (V1, . . . ). An input value (KG), which corresponds to the standard size of an article of clothing representing a given person in a clothing size system is specified via at least one input unit (EE). A control device (S) derives a control signal (SL) from the input value and outputs the control signal to the actuator, so that the actuator autonomously presets a height/firmness profile, which is adapted to physical body parameters of the person represented by the clothing size, in the lying/sitting surface. A data network (DNi) enables the control unit to output control signals (SLyx) to the actuator of a resting unit (Hyx) selected for the person in such an arrangement.

The present invention relates to a multi-function mattress composed of MagLev suspension, stretched net surface and adjustable underneath elastic cushion modules for optimized body contour-fitting and head-shoulder-neck massage by the motorized roller. This mattress design provides a unique solution to achieve the best body contour-fitting with a simple structure. The MagLev suspension technology helps generate the best support for the entire body during the sleep. It also provides comfort and relaxation that is associated with the sleep-cool technique, which is achieved through the underneath hollow structure. This mattress can be made at efficient cost to perform multi-function. The energy-efficient design also reduces its impact on the environment.

A respiratory assistance component is disclosed that changes shape when an electrical charge is provided. The amount of electrical charge that is applied may be based on values, characteristics, or user controlled parameters of the respiratory assistance system. The component may be all or part of a patient interface, a tube, a flow generator, and/or a sleep mat.

A method for correcting a massage position and a massage chair for performing the same includes allowing a shoulder height measurement module to measure a shoulder height of a user, allowing a hip bone position prediction module to predict a hip bone position through a preset prediction method by using the shoulder height measured by the shoulder height measurement module, allowing a massage position determination module to determine a plurality of determination massage positions and a plurality of correction massage positions spaced from the determination massage positions by a predetermined distance on the basis of the hip bone position predicted by the hip bone position prediction module, and allowing a massage ball assembly control module to control a massage ball assembly so as to massage the determination massage positions and the correction massage positions determined by the massage position determination module.

Spring modules for an adjustable sleeping system. At least some of the example embodiments are spring modules comprising: a spring rail, and a plurality of adjustable spring assemblies spaced along the length of the spring rail. Each adjustable spring assembly may comprise: a motor with a stator coupled to the spring rail, a lead screw coupled to the rotor of the motor, and the lead screw extending above an upper surface of the spring rail, a spring plate coupled to the lead screw, and a main spring coupled to the spring plate. Thus, the weight or force carried by each adjustable spring assembly along the spring rail is separately adjustable by a bed controller.

Adjustable sleeping system with force control. At least one example embodiment is a method of operating a sleeping system, the method including: sensing an area of a sleeping surface of the sleeping system, the area upon which a person resides, the sensing by a bed controller communicatively coupled to an array of adjustable spring assemblies arranged such that a top of each adjustable spring assembly defines an upper surface parallel to the sleeping surface; and driving a plurality of the adjustable spring assemblies being the adjustable spring assemblies beneath the area, the driving to control force distribution among the plurality of the adjustable spring assemblies.
