The pullout guide includes a retraction device configured to retract the furniture pullout part at least over a portion of the predefined pullout distance. The retraction device includes a spring configuration having a first spring and a second spring connected in parallel with respect to each other. Each of the first and second springs includes a different spring characteristic curve than the other spring and/or each of the first and second springs includes a different force-distance characteristic acting in a pullout direction of the pullout guide. ## Claims ### Claim 1 A pullout guide for a furniture pullout part configured to be pulled out from a piece of furniture over a predefined pullout distance, the pullout guide comprising: a retraction device configured to retract the furniture pullout part at least over a portion of the predefined pullout distance; the retraction device including a spring configuration having a first coiled spring and a second torsion spring connected in parallel with respect to each other; wherein the second torsion spring acts as one of a tension and compression spring during a retraction of the furniture pullout part; wherein the second torsion spring is formed from a spring steel wire bent into an S-shape; wherein each of the first and second springs includes a different spring characteristic curve than the other spring; wherein each of the springs acts in an opening and a closing direction of the pullout guide, and closing direction forces of the two springs are additive; and wherein each of the different sprint characteristic curves includes a different force-distance characteristic acting in the pullout direction of the pullout guide. ### Claim 2 (depends on 1) The pullout guide according to claim 1, wherein the first coiled spring acts as one of a tension and compression spring during a retraction of the furniture pullout part. ### Claim 3 (depends on 1) The pullout guide according to claim 1, wherein the first and second springs include different horizontal force-distance characteristics. ### Claim 4 (depends on 1) The pullout guide according to claim 1, wherein the spring steel wire has one of a rectangular and round cross-section. ### Claim 5 (depends on 1) The pullout guide according to claim 1, wherein the spring steel wire is bent into a single-curved shape. ### Claim 6 (depends on 1) The pullout guide according to claim 1, wherein the retraction device includes a base and a slide, and the first and second springs are at least partially fixed on the base and at least partially coupled to the slide. ### Claim 7 (depends on 1) The pullout guide according to claim 1, wherein a retraction force of the first spring decreases over an active retraction distance of the first spring with the retraction of the furniture pullout part. ### Claim 8 (depends on 1) The pullout guide according to claim 1, wherein a retraction force of the second spring increases with a retraction of the furniture pullout part over a portion of an active retraction distance of the second spring. ### Claim 9 (depends on 1) The pullout guide according to claim 1, wherein a retraction force of the second spring is initially negative over an active retraction distance of the second spring and then increases with a retraction of the furniture pullout part. ### Claim 10 (depends on 1) The pullout guide according to claim 1, wherein the retraction device further includes a slide and a pin and the pin acts on the torsion spring such that the torsion spring is pressed down by the pin in a maximum pullout position of the slide. ### Claim 11 (depends on 10) The pullout guide according to claim 10, wherein the torsion spring has two spaced-apart ends, the torsion spring is fixed on a housing via said spaced apart ends, said torsion spring has a bending area between the two ends, and the pin acts on said bending area. ### Claim 12 A pullout guide for a furniture pullout part configured to be pulled out from a piece of furniture over a predefined pullout distance, the pullout guide comprising: a retraction device configured to retract the furniture pullout part at least over a portion of the predefined pullout distance; the retraction device including a spring configuration having a first coiled spring and a second torsion spring connected in parallel with respect to each other; wherein the second torsion spring acts as one of a tension and compression spring during a retraction of the furniture pullout part; wherein the retraction device further includes a slide and a pin and the pin acts on the torsion spring such that the torsion spring is pressed down by the pin in a maximum pullout position of the slide; wherein the torsion spring has two spaced-apart ends, the torsion spring is fixed on a housing via said spaced apart ends, said torsion spring has a bending area between the two ends, and the pin acts on said bending area; wherein each of the first and second springs includes a different spring characteristic curve than the other spring; wherein each of the springs acts in an opening and a closing direction of the pullout guide, and closing direction forces of the two springs are additive; and wherein each of the different sprint characteristic curves includes a different force-distance characteristic acting in the pullout direction of the pullout guide.
