Abstract
A folding chair with hard arms has front and rear support tubes, left and right support tubes, chair back auxiliary tubes. The left and right support tubes are bent upward to form the arm support tubes. One end of a hard arm is pivotally connected to the upper end of the arm support tube and another end has an arm fixing shackle. A sliding element is pivotally connected at one end to the auxiliary tube and its another end is slide-connected with the hard arm. The hard arm folding chair uses a sliding structure for the arms, and it utilizes the arm fixing shackle device to enable the arms to be withdrawn with the chair. The hard arm folding chair provides support to the user for standing up and reduces deformation of the flexible seat and back material, therefore improving comfort.
