<p>A moulded plastics clamp (14) for attaching strap (16) of a lumbar support to an upright of a seat for a vehicle comprises two portions (20, 22) reinforced by ribs (52-53) and integrally joined by flexible portion (24). To engage clamp (14), portion (24) is flexed so that ridged concave sections (26, 28) enclose and contactthe upright, projection (60) being received in a hole therein. During engagement, surfaces (34, 36) on extension sections (30, 32) are guided into proximity, if not contact, by engagement of complementary tapering webs (42) and recesses (44) so that apertures (38, 40) align to receive a bolt to tighten clamp (14). Extension section (30) includes flanges (50) between which section (32) locates to prevent relative lateral movement between sections (30, 32).</p> |
