Abstract

The invention discloses a seat stretching device capable of being extended and stretched. The seat stretching device comprises a base, a linkage mechanism, a linkage side plate, a leg mechanism, a backrest mechanism, a transmission mechanism and a driving mechanism. The transmission mechanism comprises a bracket assembly, a transmission shaft and a transmission connecting rod assembly, the end part of the transmission shaft is in transmission connection with the leg mechanism through the transmission connecting rod assembly, one end of the bracket assembly is connected with the middle part of the transmission shaft, and the other end is connected to the driving mechanism; the driving mechanism comprises a driving motor, a sliding rail and a sliding block, the sliding rail is parallel to the horizontal plane, and the sliding block is connected with the transmission shaft through the bracket assembly; and when the leg mechanism and the backrest mechanism are driven from a contraction position to a limit position of complete stretching, the sliding stroke of the sliding block is 26-33 cm. The driving process of the driving mechanism is more stable and smoother, the pushing precision and pushing efficiency are improved, and the comfort of the seat is improved.

Description

technical field [0001] The invention belongs to the technical field of seats, and in particular relates to an extendable seat stretching device. Background technique [0002] As people's living standards are getting higher and higher, the requirements for smart furniture such as multifunctional sofas and seats are also getting higher and higher. The Kinetic Sofa and Seat can be adjusted between a sitting position, an extended position where only the legs are extended, and a reclined position where the legs and back are fully extended. [0003] However, the stretching device of the existing seat is usually not smooth during the posture conversion process. The driving device of the seat usually has a large driving stroke and a small stretching distance. The center of gravity of the chair support is unstable. Contents of the invention [0004] The invention aims to solve the problems of large installation space and high installation position of the existing seat driving mec...
