• at least two scissor links, each scissor link comprising a first scissor member and a second scissor member,
• a first rotational joint formed between the first and second scissor members of each one 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 neighbouring, second scissor link,
• wherein the first and the second scissor members of the first scissor link has an inner side facing each other and an outside facing away from each other;
• wherein the first scissor member and the second scissor member of the second scissor links has an inner side facing each other and an outside facing away from each other;
• and
