摘要

Improvements in the manufacture of chairs, particularly of an automatically folding seat, characterized in that they comprise a member integral with the seat rotation bolt, which cooperates automatically with a second hook member and can be released from it by simple rotation of the seat only when a body solid in a pre-established manner is placed between the aforementioned organs, the wooden coupling member being formed or/and placed such that it allows the body to move away or fall as soon as it has been separated from the other organ, so that it is possible to block it again when the seat, by the action of suitable springs, adopts the resting position after the use of the chair.
