Abstract: An impact protection controller for an electric height-adjustable desk. The controller comprises an MCU, a motor drive circuit, a motor current sampling circuit, a current amplifier circuit, a Hall pulse generator, and a Hall filter. The MCU controls the motor drive circuit. A signal transmitted by the Hall pulse generator is sent to the MCU via the Hall filter. A motor current is sampled by the motor current sampling circuit, and the result is sent to the MCU via the current amplifier circuit to detect a change of the current. The controller further comprises a shock switch provided outside of and connected to the MCU, or provided inside of the MCU. The present invention combines current detection and shock detection to improve sensitivity and reliability of impact protection.

Abstract: An electromotive furniture drive includes a drive motor including an output shaft, a lift spindle arranged in a common plane with the output shaft, and a gear assembly configured to couple the output shaft of the drive motor to the lift spindle. The gear assembly includes an intermediate shaft which intersects the common plane between the lift spindle and the output shaft.

Abstract: A lumbar support device for an item of seating furniture, in particular an armchair, includes an electromotive linear drive including a guide profile and two sliding blocks movable on the guide profile in synchronism towards one another and away from one another. Each sliding block includes a spindle nut coupled by a spindle. The linear drive is coupled to an extendable support element via a lever mechanism which includes levers connecting the sliding blocks to the support element, respectively.

Abstract: An electromotive furniture drive includes a housing having an opening, a drive motor attached to the housing and including an output shaft, and a standpipe inserted into the housing laterally in a form-fitting manner. The standpipe has an outer wall formed with a transverse groove, with a lifting spindle arranged in the standpipe. A gear assembly is arranged in the housing and configured to couple the output shaft of the drive motor to the lifting spindle. A locking element is configured to engage in the transverse groove and held in a recess in the housing.

Abstract: A telescopic tube for use in a linear drive to be applied in articles of furniture such as beds, chairs and the like has an outer tube accommodating an inner lift tube which is longitudinally displaceable within the outer tube by the linear drive and projects from the outer tube at a front end opposite to the linear drive. An end cover having a seal closes and seals the front end and prevents any media from entering the outer tube and the linear drive.

Abstract: The invention relates to reclining furniture comprising at least one sensor (6) and a warning device coupled to said sensor in order to warn about an undesired standing process of a user of the reclining furniture. The reclining furniture is characterized in that the warning device is designed to evaluate information of the at least one sensor (6) with respect to a movement and/or behavior pattern of a person using the reclining furniture in order to emit a warning signal as soon as there is an intention to leave the reclining furniture. The invention additionally relates to a method for operating a warning device of reclining furniture, said warning device being coupled to at least one sensor (6) which is arranged on the reclining furniture.

Abstract: The invention relates to a frame for supporting a top 4, 12 of a table or desk at a working height, said frame being designed for fastening legs 6, 9, in particular for height-adjustable legs 6, 8 of a desk. In order to reduce the storage costs for different table or desk sizes, the frame has a movable, in particular longitudinally movable design.

Abstract: The invention discloses a single motor adjustable multi-function bed, which comprises a fixed mechanism, a movable mechanism and a back panel. The fixed mechanism comprises a fixed frame, a movable rail is arranged symmetrically on both sides of the fixed frame, and one end of the fixed frame is provided with a first cross bar. The movable mechanism comprises a movable frame, a sliding part arranged symmetrically on both sides of the movable frame, a second cross bar arranged in the middle part of the movable frame, the movable rail engages with the sliding part, and the bottom of the back panel is connected with the first cross bar. And a driver is provided between the first cross bar and the second cross bar. The invention realizes the angle adjustment and the bed length adjustment function by the movable rail in conjunction with the sliding part.
