A method for producing an activation lever for a longitudinal adjuster involves providing a tubular blank, pressing an end portion of the blank from a first direction and pressing the end portion of the blank from a second direction perpendicular to the first direction, whereby only forming of the external contour of the blank takes place. An activation lever for activating a locking unit for securing a first seat rail relative to a second seat rail where the activation lever, in an end portion interacts with a spring element and/or a locking element of the longitudinal adjuster, has a deformed surface which is closed perpendicularly to the longitudinal extent of the activation lever. A longitudinal adjuster for a vehicle seat has the activation lever.
