A friction stay comprises a guide track 10, first and second slides 16, 18 movable along the guide track 10 and connected by a linkage arrangement to a vent arm 20. A retaining device 38, 40 is operable to restrict movement of the first slide 16 and is releasable by a release mechanism 44 associated with the second slide 18. A restrictor 50 is operable to prevent operation of the release mechanism 44 to release the retaining device 10 other than when the second slide 18 occupies a predetermined position relative to the track 10, which may be the fully open position. The retaining device may comprise a spring biased tooth 38 engagable with a projection 40 in the base of the track. The release mechanism 44 may secure the first and second slides 16, 27 to one another and may comprise a lever 44 including a hook region 46 which may engage with an opening 48 in the first slide to disengage the tooth 38 with the track. |
