| 摘要 |
The invention relates to an adjuster device (1) for adjusting the length and fastening of a web type strap (12), and in particular to an adjuster device (1) intended to be used together with a child restraint harness as part of a child vehicle seat. The adjuster device according to the invention allows, when the adjuster is in the open, release position, the strap to be easily pulled and freely move through the adjuster in both directions whereas the strap, when the adjuster is in the closed, fastening position, is securely fastened (without any risk for slippage) while still allowing the strap to be easily tightened by pulling the strap in one direction only. The present device does not cause wear and tear of the web, prevents slippage and is easy to use. |

1. An adjuster device (1) for adjusting the length and fastening of a web type strap (12), said device (1) characterized in comprising:
a base (2) having a bottom frame (3) extending in a first plane (A), said base (2) defining at least one longitudinally elongated slot (4); an operating handle (6) comprising a first pin (7) extending along a first axis (C), said operating handle (6) being pivotally arranged to the base (2) about a pivot axis (D) being parallel to said first plane (A), and said operating handle being movable between a release position and a fastening position; a second pin (11) extending along a second axis (E) being parallel to said pivot axis (D), said second pin (11) being engaged in said slot (4) and slidably movable therein between a first end position and a second end position; wherein a strap entrance (13) is defined between said second pin (11) and the bottom frame (3) such that a strap (12), having a free first strap end (12a) outside of the strap entrance (13), is receivable through the strap entrance (13), thence around the first pin (7) and thence through a strap exit (14) arranged in an adjacent relation to said bottom frame (3) to thereby provide a second strap end (12b) connectable to a child restraint harness; and wherein the device (1) being configured such that when the operating handle (6) is in its release position, the second pin (11) is freely movable in said slot (4) between the first end position and the second end position, and when the operating handle (6) is in its fastening position, the second pin (11) is squeezed to said first end position by parts of the strap (12c) brought into contact while still allowing the strap (12) to be tightened by pulling the free first strap end (12a) in a first direction (X1), whereas an increased tension on the second strap end causes a restraining action arising at least in part from friction between said parts of the strap (12c). |
