A handset cable reel for use e.g. in passenger aircraft comprises a spool fitted with a rewind bias spring, the spool also having peripheral teeth 82. These interact with an oscillating pawl 62, a ratchet/star wheel 60 and a pawl 57 so that, after the cable has been extended a certain amount, repeat

A handset cable reel for use e.g. in passenger aircraft comprises a spool fitted with a rewind bias spring, the spool also having peripheral teeth 82. These interact with an oscillating pawl 62, a ratchet/star wheel 60 and a pawl 57 so that, after the cable has been extended a certain amount, repeatedly releasing and then pulling on the cable will alternately lock the spool to prevent retraction of the cable by the rewind bias, and then allow such retraction under the influence of the rewind spring. A driving key 100 on the spool indexes a cam wheel 88 for rotation so that as the final length of the cable is being rewound, a cam surface 96 rotates the pawl 57 about a pin 48 so that it no longer co-operates with the star/ratchet wheel 60 and the cable remains under spring tension even if inadvertently tugged.
