ABSTRACT:
An improved locking assembly for a folding seat is disclosed. The assembly includes a support plate adapted to be fixedly mounted to a step at its lower surface. The seat is supported by a support member when the seat is in its support position. The assembly also includes a broad hook pivotally connected at one end thereof to the support plate at a position substantially midway between the sides of the seat to hold the support member in locking relationship with the step to prevent the step from unintentionally moving out of its support position.
