A calibration spring tension adjuster for a seat belt tension sensor comprising a fixed part (1), a movable part (2), a calibration spring (3), and a holder (4), wherein the fixed part (1) and the movable part (2) are adjacent to each other and comprise mutually facing stepped helical faces (7,8) arranged so that the movable part (2) can be rotated relative to the fixed part (1) causing the steps to slide over each other causing a gap between the stepped faces (7,8) to increase and compressing the spring. The steps can be arranged so that movement of the movable part (2) in one direction is resisted. The holder (4) is arranged to attach to the fixed part (1) and the spring (3) is held between an abutment face (10) of the holder (4) and non-stepped face (9) of the movable part (2). <??>A method of assembling and calibrating a sub-assembly for a seat belt tension sensor is also described. <IMAGE> |
