The slot includes an intermediate transfer portion obliquely related to a guide portion thereof in which the pin is received when the seat is in the seating position. The slot is generally U-shaped with the transfer portion defining the bight thereof and extending at a substantial angle to the horizontal when the seat is in the seating position. The guide portion extends at a small angle to the horizontal when the seat is in the seating position. The latching portion extends generally perpendicular to the transfer portion.
