Secondary latch for a tire carrier

摘要

A tire carrier assembly for storing a spare tire of a motor vehicle includes a tire carrier for supporting the spare tire and having a swivel with a shank portion and a head portion along the shank portion, a winch assembly operably connected to the tire carrier with a cable or rope to raise and lower the tire carrier between upper and lower positions, a housing assembly forming a horizontal support surface, and a secondary latch assembly secured to the housing assembly and adapted to selectively confine the tire carrier in the upper position. The secondary latch assembly includes a sliding latch member supported by the horizontal support surface and an actuator adapted to selectively move the latch member along a linear path between a locking position and an unlocking position. The latch member is adapted to permit passage of the of the shank portion but not the head portion past the latch member when the latch member is in the locking position and to permit passage of both the shank portion and the head portion past the latch member when the latch member is in the unlocking position. The actuator includes an arm pivotable between a locking position and an unlocking position and having one end extending through an opening formed in the latch member such that pivotal movement of the arm linearly moves the latch member. The actuator further includes a spring member biasing the arm to the locking position. Various alternative embodiments are also disclosed wherein the actuator arm is connected to the latch member with a pin-and-slot connection and wherein the latch member has resilient fingers.
