Description

Turnover type seat armrest and seat Technical Field The application relates to the technical field of seat structures, in particular to a turnover seat armrest and a seat. Background Armrests are an important component of a chair, mainly for supporting the arms of a user. Armrests of existing seats are generally classified as stationary or mobile folding. The fixed armrests are fixed on the left side and the right side of the seat and can not move, and some seats are movably folded armrests for facilitating the users to get in and out of the seat (such as automobile seats) or folding the seat (wheelchair). However, current movable folding armrests are generally only capable of swinging in an up-and-down direction to raise or lower the armrests, such as in a car seat, or to fold the armrests back and forth, such as in a wheelchair. After the armrests are folded, the armrests are still located on the outer side of the seat body, and occupied space is reserved, so that the armrests cannot be hidden in the seat after being folded, and the armrests are inconvenient to use in some armless application occasions, such as the office chairs cannot be spliced side by side for noon break, and are inconvenient to place side by side for transportation.
