Abstract
A scissor-type guide for guiding extension and retraction of lamellae. The scissor-type guide includes at least two scissor links, each having a first and second scissor members. The guide further includes a first rotational joint formed between the scissor members of each of the scissor links, and two second rotational joints formed between first ends of a first scissor member and a second scissor member of a first scissor link, and respective ones of second ends of a first scissor member and a second scissor member of a neighboring second scissor link. A spring member is formed between the scissor members at a first rotational joint, or between a first scissor member of the first scissor link and the first scissor member of a neighboring second scissor link at a second rotational joint.

Abstract
A scissor-type guide (20) for guiding extension and retraction of lamellae, said scissor-type guide (20) comprising - at least two scissor links (23, 123), each scissor link comprising a first scissor member (24, 124) and a second scissor member (25, 125), - a first rotational joint (26, 126) formed between the first and second scissor members (24, 124; 25, 125) of each one of the scissor links (23, 123), and - two second rotational joints (27) formed between first ends (24', 25') of a first scissor member (24) and a second scissor member (25) of a first scissor link (23), and respective ones of second ends (124", 125") of a first scissor member (124) and a second scissor member (125) of a neighbouring, second scissor link (123); wherein a spring member (300) is formed between the first scissor member (24, 124) and the second scissor member (25, 125) at a first rotational joint (26, 126) of the scissor-type guide (20), or between a first scissor member (24) of the first scissor link (23) and the first scissor member (124) of a neighbouring second scissor link (123) at a second rotational joint (27) of the scissor-type guide (20).
