Finger pinch protection for an entrance system

Abstract

Disclosed is a method () of providing finger pinch protection at a hinge area of a swing door-based entrance system () having a motorized automatic door operator () for opening () of the swing door () in an automatic mode of the entrance system (), wherein the entrance system () also has a manual mode in which a human user may cause opening and closing of the swing door () by manual force. The method involves monitoring (), by a first sensor function (S), for presence of a person or object in a first zone (PD) at the first door leaf surface (-) and non-proximate to a vertical door edge (). The method also involves monitoring, by a second sensor function (S), for presence of a person or object in a second zone (PDHA) at the first door leaf surface (-) and proximate to said vertical door edge (). When any of the first sensor function (S) or second sensor function (S) detects presence in the first zone (PD) or second zone (PDHA) in the automatic mode during an ongoing opening of the swing door (), the automatic door operator () is controlled so as to stop opening of the swing door (). When the second sensor function (S) detects presence in the second zone (PDHA) in the manual mode, the automatic door operator () is controlled so as to counteract an attempt by a human user to manually open the swing door (). A corresponding entrance system () is also disclosed.
