USPTO Abstract

The present disclosure relates to an activation assembly for a medicament delivery device (1), wherein the activation assembly comprises: a delivery member cover (5) , a movable sleeve (17), and an activation sleeve (19) , wherein the delivery member cover (5) is configured to be moved in an axial direction between a first position relative to the movable sleeve (17) and a second position relative to the movable sleeve (17) wherein the delivery member cover (5) is configured to axially displace the activation sleeve (19) in a distal direction when the delivery member cover (5) is moved towards the second position, the activation sleeve (19) being configured to thereby provide a first actuation of a sensor (31) of an electronics assembly (29) of the medicament delivery device (1), wherein the activation sleeve (19) is configured to move in the proximal direction when the delivery member cover (5) returns from the second position to the first position, thereby providing a second actuation of the sensor (31), and wherein the movable sleeve (17) is configured to prevent the delivery member cover (5) from moving from the first position to the second position when the delivery member cover (5) has returned from the second position to the first position.
