Movable backrest and drive mechanism thereof

Abstract

The invention relates to an adjustable backrest and a dynamic mechanism thereof, which is the adjustable backrest that one or more than one adjustable backrest that can adjust the inclination by the electric way are arranged on the original backrest of a bed or a recliner; the top end of the backrest is pulled by a traction loop tensioned on the original backrest; the traction loop can be driven to lead the top end of the adjustable backrest to move upwardly and downwardly; the aim of adjusting the inclination of the adjustable backrest can be reached by the function of an adjustable support. The latest research abroad indicates that the semi-reclining position that keeps the leg and the spine to be about 135 degrees is the ideal sitting position which is beneficial to the health of the spine; the system can be adjusted to the posture conveniently. The use of the system can not only bring the convenience and comfort to the leisure life of people, but also bring health to the spines of users. The system can be used in the household life and can be widely used in high-grade places of beaches, shower, leisure, holidays, hotels, restaurants, and the like, or special places of hospitals or nursing houses, etc.

Description

Technical field: [0001] furniture Background technique: [0002] At present, most of the backrests at the head of the bed are fixed backrests that cannot be adjusted arbitrarily, which cannot be achieved for people who want to lie half-ly on the bed for leisure; degree, but most of them require manual operation. And in the existing patented technology, as the patent No. 02205955.5, the adjustable inclination angle of the backrest described in the patent literature is not only because it is manual, but also because the designed adjustment gear is several fixed gears, so the number of gears Limited, inconvenient to use, and its structure is slightly complicated. Invention content: [0003] The invention relates to a backrest frame, a movable backrest installed on the backrest frame, a traction loop for pulling the movable backrest, and a power mechanism for driving the traction loop. [0004] Described back frame is the upright backrest (frame) of a pair of bedside frames...
