A latch assembly with a first leg securing to a seat bottom and a second leg pivotally engaged to an upper end of a stanchion mount. A sector is pivotally slaved to the second leg opposing the stanchion and exhibits a bottom shoulder projection separating into first and second surface locations. A pendulum pivotally secures to the stanchion and seats against a first sector location with the seat bottom in a downward position. The seat bottom is rotated in an upward direction, causing a detent lever to pivot out of engagement with a notch location of a supporting frame and travel along an edge extending profile thereof, simultaneous with the sector displacing relative to the pendulum. The detent lever reestablishes seating engagement with a second notch location concurrent with the pendulum pivoting into engagement with a second sector location corresponding to an upwardly rotated position of the seat.
