Abstract
A headrail for a motorized window covering is described that includes a motor and a gearbox coupled to the motor that is configured to actuate a window covering. The headrail includes a safety detector with one or more sensors that detect an irregular strain when the window covering is being raised. The headrail may further comprise a recoil mechanism or a deactivation mechanism to reduce the likelihood of damage to the window coverings and/or individuals caught or tangled in the window covering.
