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 a 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) com
1. An adjuster device (1) for adjusting a 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; andwherein 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). 2. An adjuster device (1) according to claim 1, wherein said first axis (C) and said second axis (E) are parallel and define a second plane (B), and said device (1) being configured such that when the operating handle (6) is in its release position, the second plane (B) forms an angle (α) of equal to or more than 30° with the first plane (A) to allow the strap (12) to move freely in either direction and when the operating handle (6) is in its fastening position, the second plane (B) forms an angle (β) of less than 30° with the first plane (A). 3. An adjuster device (1) according to claim 2, wherein the release position angle (α) is at least 30° greater than the fastening position angle (β). 4. An adjuster device (1) according to claim 2, wherein the angle (α) formed between the second plane (B) and the first plane (A) when the operating handle (6) is in its release position is greater than the angle formed between the longitudinal centre line of said longitudinally elongated slot (4) and the first plane (A). 5. An adjuster device (1) according to claim 1, wherein said slot (4) is extending at least partially in a direction substantially vertical to said first plane (A). 6. An adjuster device (1) according to claim 1, wherein the first pin (7) is movable about said first axis (C). 7. An adjuster device (1) according to claim 1, wherein the first pin (7) is fixed about said first axis (C). 8. An adjuster device (1) according to claim 7, wherein the first pin (7) is integral with the operating handle (6). 9. An adjuster device according to claim 1, wherein the second pin (11) is movable about said second axis (E). 10. An adjuster device (1) according to claim 1, wherein a strap exit (14a) is provided by an opening in the bottom frame (3), through which strap exit (14a) the second strap end (12b) can be passed in a second direction (Y) substantially perpendicular to said first direction (X1). 11. An adjuster device (1) according to claim 1, wherein the operating handle (6) comprises a pivot pin (15) extending along the pivot axis (D). 12. An adjuster device according to claim 11, wherein a strap exit (14b) is defined between said pivot pin (15) and the bottom frame (3), through which strap exit (14b) the second strap end (12b) can be passed in a third direction (X2) substantially opposite to said first direction (X2). 13. An adjuster device according to claim 1, further comprising a third pin (17) extending along a third axis parallel to said pivot axis (D), wherein a strap exit (14b) is defined between said third pin (17) and the bottom frame (3), through which strap exit (14b) the second strap end (12b) can be passed in a third direction (X2) substantially opposite to said first direction (X1). 14. An adjuster device according to claim 1, further comprising a guiding member (17′), wherein a strap exit (14b) is defined between said guiding member (17′) and the bottom frame (3), through which strap exit (14b) the second strap end (12b) can be passed in a third direction (X2) substantially opposite to said first direction (X1). 15. An adjuster device according to claim 1, further comprising biasing means (16) for biasing the operating handle (6) towards the base (2). 16. An adjuster device according to claim 15, wherein the biasing means (16) comprises at least one tension spring (16) coupled to the operating handle (6) and the base (2). 17. A child vehicle seat (18) comprising: a cushioned seat shell having a seat portion (19) and a back portion (20) integrally connected together;an adjustable child restraint harness (21) comprising web type straps (22, 23, 24) for restraining and securing a child in the seat shell, where the restraint harness is mounted to said seat shell; andan adjuster device (1) for adjusting a length and fastening of a web type strap (12) connectable to said child restraint harness (21) whereby operation of said adjuster device (1) allows loosening or tightening of the harness (21), characterized in that the adjuster device (1) is an adjuster device (1) according to claim 1.
