Abstract
A cervical collar has an anterior component including a lower support that is adjustable in angle relative to a main support. The lower support is hingedly connected to the main support at first and second end portions. An elongate element engages the first and second end portions. A lock mechanism is operative connected to the elongate element, and is arranged for locking rotation of the lower support relative to the main support, by moving the elongate element between locked and unlocked conditions.

A cervical collar having an anterior component arranged for connecting to a posterior component, the anterior component comprising:
- a main support;
- a lower support hingedly connected to the main support at first and second end portions of the anterior component;
- a lock mechanism arranged for locking rotation of the lower support relative to the main support simultaneously at the first and second end portions;
- an elongate element operatively connected to the lock mechanism and extending to the first and second end portions such that actuation of the lock mechanism moves the elongate element relative to the first and second end portions to lock and unlock the main support relative to the lower support.
A cervical collar having an anterior component arranged for connecting to a posterior component, the anterior component comprising:
- a main support;
- a lower support hingedly connected to the main support at first and second end portions of the anterior component;
- an elongate element having first and second ends engaging the first and second end portions, the first and second ends arranged for adjusting relative to the first and second end portions;
- a lock mechanism arranged for locking rotation of the lower support relative to the main support, and moving the elongate element between locked and unlocked conditions such that the elongate element is biased into the locked condition.
A method for adjusting an angle defined between a main support and a lower support of an anterior component of a cervical collar, the method comprising:
- moving an elongate element relative to the main support and the lower support;
- disengaging a part of the main support from a corresponding part of the elongate element to unlock the lower support from the main support;
- moving the lower support relative to the main support;
- engaging part of the main support to the corresponding part of the elongate element to lock the lower support to the main support.
