Abstract
A safety restraint adapted for securing a personal mobility vehicle in a transport vehicle, against movement in a direction opposite to the direction of normal motion of the transport vehicle, the safety restraint comprising: a retractor comprising a spool on which an elongate piece of material is wound; the elongate material being configured to be attached at one end to the personal mobility vehicle; a slider bar adapted to be fixed to the transport vehicle; and wherein the retractor is mounted on the slider bar, in a manner which allows the retractor to slide in the direction of normal motion of the transport vehicle, and prevents the retractor moving in the opposite direction on the slider bar.
Claims20
A safety restraint adapted for securing a personal mobility vehicle in a transport vehicle, against movement of the personal mobility vehicle in a direction opposite to the direction of normal motion of the transport vehicle, the safety restraint comprising:
- a retractor comprising a spool on which an elongate piece of material is wound;
- the elongate material being configured to be attached at one end to the personal mobility vehicle;
- a slider bar adapted to be fixed to the transport vehicle;
- and
- wherein the retractor is mounted on the slider bar, in a manner which allows the retractor to slide in the direction of normal motion of the transport vehicle, and prevents the retractor moving in the opposite direction on the slider bar.
A safety restraint adapted for securing a personal mobility vehicle in a transport vehicle, against movement of the personal mobility vehicle in a direction opposite to the direction of normal motion of the transport vehicle, the safety restraint comprising:
- a spool holding a length of material for fastening to the personal mobility vehicle, the spool being rotatably mounted in a retractor and being biased to wind in loose material;
- a locking mechanism operatively associated with the spool and adapted to lock the spool against rotation in a direction to pay out webbing but to allow retraction in a direction to wind in the material onto the spool.
A safety restraint adapted for securing a personal mobility vehicle in a transport vehicle, against movement of the personal mobility vehicle in a direction opposite to the direction of normal motion of the transport vehicle, the safety restraint comprising:
- a retractor on which an elongate piece of material is wound;
- the elongate material comprising means for attachment of one end to the personal mobility vehicle;
- a slider bar adapted to be fixed to the transport vehicle;
- wherein the retractor is mounted on the slider bar, in a manner which allows the retractor to slide in the direction of normal motion of the transport vehicle, and prevents the retractor moving in the opposite direction on the slider bar;
- and
- the retractor comprises:
- a locking mechanism comprising a web sensor member for causing the retractor to lock when the elongate member is withdrawn at a velocity above a predetermined velocity, the locking mechanism comprising an inertia member mounted for rotation coaxially with the spool so as to rotate with the spool under normal usage and to lock the spool against rotation when the inertia member lags the spool.
