US Patent 9435605 Safety trigger mechanism for a crossbow

In at least one embodiment, a crossbow trigger assembly comprises a housing, a string catch and a trigger arranged to release the string catch. A safety member is moveable between safe and fire orientations, which prevents actuation of the trigger while in the safe orientation. An arrow sensing member is moveable between first and second orientations and prevents the safety member from assuming the fire orientation when the arrow sensing member is in the first orientation.
