A bimodal bracket with a shared spindle interface lets wheelchair ramps switch from manual to power mode with less retrofit time and cost.

A solenoid and cable-operated claw latch secures wheelchairs in vehicles while enabling quick, low-effort engagement and release.

Automatic axle and adapter restraints let autonomous vehicles secure many wheelchair types without manual adjustment or operator help.

A hinged modular side barrier uses biasing and mechanical locking to fold below the floor yet stay securely unfolded during ramp use.

A wheel-and-track ramp assembly stows below the vehicle floor, then deploys flush for smooth wheelchair entry without losing cabin space.

A bimodal bracket and shared ramp assembly let wheelchair ramps switch between manual and power modes with less conversion time and cost.

A pivoting baseplate cover doubles as an inboard barrier to ease wheelchair lift entry while preventing roll-off at the vehicle door.

Pivoting side rails, cam arms, and a guide assembly let a vehicle ramp stow compactly yet deploy smoothly for wheelchair entry and exit.

A cable-actuated clamping seat base locks and releases from the vehicle floor to improve accessible seating, repositioning, and wheelchair entry.

A movable deck panel lets a side-entry wheelchair ramp store as part of the vehicle floor, avoiding wider door modifications.

A closed-loop retractor restraint doubles webbing length to secure heavier wheelchairs in tight vehicle spaces with less clutter and simpler installation.

A bendable mounting member lets a wheelchair ramp plate swing up over obstacles, protecting drivability without heavy actuators.

A tracked linkage and roller ramp assembly raises a stowed vehicle ramp flush with the floor for wheelchair access without losing cabin space.

Front and rear wheel securing members clamp a wheelchair against inertial movement in a vehicle, improving occupant safety during acceleration and braking.

A geared ramp uses translation and pivoting to stow below the vehicle floor, then deploy flush with lifted side rails for wheelchair entry.

A door-integrated cradle and track-cart mechanism stores a mobility aid in door thickness, then deploys it beside the seat for easy access.

A pivotable ramp, sensing guidance, stop bars, and a movable driver seat help wheelchair users enter, position securely, and drive independently.

An integrated chock and coupling mechanism secures wheelchairs in vehicles with fewer manual steps, optional engagement sensing, and easier independent use.

Passenger-specific wheelchair data lets vehicle docks auto-set height, cutting dwell time and removing manual adjustment risk.

Slide-out trays and lockable compartments keep emergency duffle bags dry, secure, and quickly reachable on response vehicles.

A tilting guide with sliding support elements reduces rescuer lifting effort while keeping stretcher loading fast, stable, and comfortable.

A movable wheelchair platform lets taxis switch between standard seating and disabled access without vehicle re-approval or dedicated fleets.

Modular chocks, couplings, and sensing alerts let standard vehicles secure wheelchairs in adjustable positions without full interior redesign.

A side-mounted van lift replaces rear loading to avoid traffic-lane obstruction, reduce rear clearance needs, and ease wheelchair boarding.

A receiver pan and pivoting extender retrofit wheelchair access at lower cost without changing the vehicle roofline or road clearance.

A sensor and stop member detect restraint withdrawal, prevent over-retraction jamming, and protect vehicle surfaces.

A hinged safety plate rises when the wheelchair lift reaches ground level, preventing roll-out during vehicle access.

A wheel-driven linkage raises the siderail during ramp deployment, keeping the ramp flush with the vehicle floor for wheelchair access.
