A compliant bed-mounted tire carrier uses slider and ball joints to preserve cargo security while reducing frame stress during articulation.

A fixed vehicle cabinet uses an extracted drawer to pivot the spare tire downward, reducing lifting effort and mechanism complexity.

A spring-loaded retainer assembly uses opposed actuators to release a spare tire from its storage post.

Arresting device allows rotation under crash conditions to dissipate impact energy and prevent cable damage.

An eyelet bracket assembly uses a rod and spring clip to secure spare wheels via rim bolt holes.

A spare tire carrier fuel tank uses a segmented mounting system to accommodate various carriers.

A vehicle luggage compartment lid adjusts position within a recessed rear panel to accommodate different spare tire sizes.

Flared cable outlet guides connecting post to store spare wheel in inclined position, increasing vehicle departure angle.

Pivoting support frame releases stud upon impact to reposition spare wheel and protect fuel tank.

A spare wheel cradle retaining assembly integrates a compensating portion below the primary connection area to prevent basket fall during fixing deficiencies.

A pivotable spare tire carrier uses a locking member to secure the mount in adjustable positions.

Double cable hoist lowers tire carrier vertically to resolve space constraints from fuel tank placement.

A spare tire presentation apparatus pivots a wheel assembly via a four-bar linkage and sliding platform to reposition the tire.

A retractable tire retainer lowers a spare wheel to ground level using a cable and winch mechanism, eliminating the need to crawl under the vehicle.

Asymmetric sequential hooks prevent theft and reduce vibration noise in spare wheel carriers.

A pneumatic spare tire holder uses a crank and rope to extract the tire from beneath the trailer.

A hoist drive mechanism uses frangible connectors to break under excessive load, enabling controlled cable payout.

Segmented hinge assemblies with localized reinforcement distribute heavy loads to resolve strength versus stability trade-offs.

A vehicle spare wheel actuation device uses a worm screw and toothed wheel to generate friction against the flexible cable.

A spare wheel lifting device integrates a safety mechanism to confirm proper anchorage through visual feedback.

Radial alignment fins self-center a wheel cover on a spare tire, sealing the concave space to minimize air swirl and debris ingress.

A reversible load floor integrates a vertical container over the spare tire for secure item storage.

Tiered support elements engage beneath a pivotably mounted loading floor to prevent structural bending and bowing under heavy loads during height adjustment.

A tire lift assembly uses rotating handles to engage and disengage a vehicle spare tire for manual handling.

Segmented centering portions with curved guide plates simplify cable placement during assembly, reducing handling precision requirements.

A rear tire carrier pivots between vertical storage and horizontal loading positions to enable solo spare tire installation.

Locking means constrain the arm in its first position, preventing movement when the cable snaps and ensuring the wheel remains attached.

Segmented wire and multi-point hinges retain the wheel during rollovers, protecting electrical components from impact damage.

An automated raising and lowering mechanism replaces manual cranking, enabling lateral extension of the spare tire from underbody storage.

A vehicle tool storage device combines a lightweight foamed first member with a rigid plate-shaped second member.

A spare wheel lifting unit employs a spring-loaded safety pawl to lock the power shaft, preventing unintended release caused by vehicle impacts and vibrations.

Interfering indented surfaces hinder rotatable element movement, preventing unintentional lowering of heavy spare wheels caused by vehicle vibrations.

Segmented shaft bolts and intermediary sockets prevent theft by restricting access to the winding mechanism.

A spare tire mount uses a worm screw reel to lift heavy loads from the rear bumper.

A modular tire carrier uses a pivot mechanism to switch between vertical and horizontal orientations on a bedslide.

A curved wire structure transitions between lowered and raised positions to secure wheels within a vehicle storage compartment.

Hydraulic cylinders tilt a rolling tire rack toward the cab, resolving the contradiction between stable storage and manual lifting effort.

A tire storage device secures to a semi-truck frame and includes a lifting mechanism for wheel handling.

A vehicle cargo handling system uses a movable platform and lifting means to position loads vertically.

Perimeter studs and a notched clamp secure the wheel to the floor pan, eliminating visibility issues caused by central medallions blocking access.

A retractable floor assembly moves along guide tracks to cover or expose a recessed storage compartment in vehicle cargo areas.
