L-track fitting including safety lock visual pin

A retractor assembly for retaining a wheelchair in a passenger vehicle, comprising:

• a retractor body configured for attachment to a retractable member mounted onto a surface of the passenger vehicle, wherein the retractable member is configured for securing the wheelchair against movement inside the passenger vehicle;
• a fitting for engaging an L-track mounted to a floor surface of the passenger vehicle;
• a pivotal connection for pivotally connecting the retractor body to the fitting;
• wherein the fitting comprises:
• a bottom portion including a row of circular disks configured to be received within a corresponding row of circular apertures formed in a surface of the L-track, wherein the fitting is configured to slide along a longitudinal length of the L-track to enable the circular discs to be retained within a channel beneath opposing ledges formed in the surface of the L-track;
• and
• a retractable lock mechanism configured to retract along the fitting in a direction perpendicular to the longitudinal length, retracting between a locked position and an unlocked position, and having circular engagement portions for engaging the circular apertures of the L-track when in the locked position, to thereby prevent the fitting from sliding along the longitudinal length, wherein the retractable lock mechanism further comprises cylindrical members configured to retractably move inside cylindrical bores formed within the fitting, wherein the circular engagement portions are formed at respective bottom ends of the cylindrical members, wherein the retractable lock mechanism is defined by a solid top portion with a pair of the cylindrical members connected thereto, which extend moveably into a respective pair of the cylindrical bores.
