Problems solved by technology

Therefore, when the angle is changed downward, pull up the armrest once it exceeds the adjustment range, release the locked state through the release mechanism, then pull it down to the lower limit position, reset it through the recovery mechanism, and then pull it up to the desired position. The troublesome operation of the angle is forced to
In addition, if this operation fails, it is necessary to perform a very troublesome operation in which the same operation is performed again

Abstract

An armrest apparatus including an arm, which is fitted to a drum provided on a seat side member, and a coil spring, which is provided on the drum, wherein one end of the spring is fixed to the arm-rest member and another end of the spring, a free end, is curved outwardly in the direction away from the center axis of the drum, and this coil spring is loosely wound around the drum so as to tighten when the arm-rest member is rotated downward, and further a coil end receiving surface that receives the curved part of the coil spring is provided in the drum. When the arm-rest member is rotated downward and reaches a predetermined set angle, the coil end receiving surface receives the curved part of the coil spring, so that the coil spring tightens the drum by a downward load applied to the arm, restricting the downward rotation of the arm.

Description

technical field [0001] The present invention relates to an armrest device provided on various seat seats including automobile seats. Background technique [0002] There is a mechanism generally called a spring lock, in which the inner diameter of the coil spring wound on the fixed shaft is smaller than the outer diameter of the shaft, and if it is in a tightened state at ordinary times, the coil spring can be moved in the direction of rewinding (loosening) direction) to rotate freely, however, in the winding direction (tightening direction), the coil spring fastens the shaft and restricts its rotation through its frictional resistance. This mechanism is of the type used for, for example, an armrest of a car (Patent Document 1). According to this mechanism, although it has the advantage of simple structure, in normal times, the locking force depends on the frictional resistance corresponding to the fastening force of the coil spring wound in the state fastened to the shaft, ...
