Abstract: An emergency locking passenger seat belt retractor is fitted with a pyrotechnic pretensioner actuator (221) which acts via a cable wound on a drum (213), the drum being located on frangible supports in a clutch housing and having internally formed cam surfaces which can act upon frangibly supported intermediate rollers (215) to displace them generally radially inwards to drivingly engage a part of the webbing reel to tighten the belt. Advantageously the drum and the locking rollers are supported on frangible pegs moulded with shim or plate members (222a, 222b), disposed on each side of the drum (213).

Abstract: A pretensioner latching mechanism having a main anchorage member (45) to be fixed to a frame (60) of a slideably adjustable vehicle seat, a further member (52) slideable along the first member under the action of a remote vehicle body mounted pretensioner through a bowden cable (49; 50) to shorten and latch an anchorage assembly (41, 42, 43, 45) by virtue of abutment of a spring loaded latch member (56) with one of a succession of abutments provided by apertures (46) of the main anchorage member.

Abstract: A Christmas tree stand comprises a lower, upwardly-open, downwardly-tapering socket for receiving the lower end of the trunk of the tree, an outer wall surrounding the socket and a top wall of a resilient plastics material capping the outer wall. A central aperture is formed through the top wall to overlie the socket and of a diameter substantially equal to that of the smallest trunk to be received within the stand, a plurality of substantially radial slots being formed in the top wall to define a plurality of leaves each of generally truncated sector shape and resiliently yieldable on the insertion therethrough and withdrawal therefrom of the trunk.
