In an acceleration device including a carrier element movably disposed in a housing together with a first energy store which is connected to the carrier element for moving the carrier element from a locked parking position to an end position while its energy is being discharged, a second energy store, which is charged with an initial energy amount when the carrier element is in the parking position, is associated with a guide element and is discharged upon release of the carrier element from the parking position while the carrier element is moved to an end position opposite the parking position. The second energy store, while being discharged to a residual energy amount, controls, by means of the guide element, the energy change rate of the first energy store at least in a part of its discharge time interval.

1. An acceleration device (50) including: a housing (11), a carrier element (40) movably supported in the housing (11), and a first energy store (52) of low stiffness disposed in the housing (11) and connected to the carrier element (40) for moving the carrier element (40) from a force or form-locked parking position (1) to an end position (2) by a discharge of the first energy store (52), said acceleration device (50) including a guide arrangement (60) with a second energy store (62) of higher stiffness than that of the first energy store (52), both energy stores (52, 62) being charged to initial energy values when the carrier element (40) is in the parking position (1) and being discharged to residual energy values during movement of the carrier element (40) to the end position,the guide arrangement (60) including a guide element (61) for firmly guiding the first energy store (52), andthe second energy store (62), which, upon the release of the carrier element (40) from its parking position (1) by an external operating element, is discharged from its initial energy value to its residual energy value while moving the carrier element (40) toward its end position (2), controlling, by means of the guide element (61), the energy change rate of the first energy store (52) at least in a partial interval of the discharge interval of the first energy store (52); wherein the guide arrangement (60) is guided in the housing (11) in a straight line guide structure (14) and the carrier element (40) is guided in a guide track (21) extending essentially parallel to the guide structure (14) and a deceleration device (30) including a piston rod (34) is arranged in alignment with the guide track (21) with the piston rod (34) being connected to the carrier element (40). 2. The acceleration device according to claim 1, wherein a stroke length of the guide arrangement (60) is limited by means of at least one stop (15, 16). 3. The acceleration device according to claim 2, wherein the at least one stop (15, 16) is adjustable. 4. The acceleration device according to claim 1, wherein the discharge time interval of the first energy store (52) is at least equal the discharge time interval of the second energy store (62). 5. The acceleration device according to claim 4, wherein the discharge intervals of the first energy store (52) and the second energy store (62) end at the same point in time. 6. The acceleration device according to claim 1, wherein at least the first energy store (52) is a tension spring (53). 7. The acceleration device according to claim 6, wherein the tension spring (53) extends at least partially around a redirecting structure (70) supported by the guide arrangement (60). 8. A combined deceleration and acceleration device (10) including an acceleration device (50) including: a housing (11), a carrier element (40) movably supported in the housing (11), and a first energy store (52) of low stiffness disposed in the housing (11) and connected to the carrier element (40) for moving the carrier element (40) from a force or form-locked parking position (1) to an end position (2) by a discharge of the first energy store (52) from an initial energy value to a residual energy value, said acceleration device (50) including a guide arrangement (60) with a second energy store (62) of a stiffness higher than that of the first energy store (52) which is also charged to an initial energy value when the carrier element (40) is in the parking position (1),the guide arrangement (60) including a guide element (61) for firmly guiding the first energy store (52), and the second energy store (62), which, upon the release of the carrier element (40) from its parking position by an external operating element, is discharged from an initial energy value to a residual energy value, controlling, by means of the guide element (61), the energy change rate of the first energy store (52) at least in a partial interval of the discharge interval of the first energy store (52) at the end of the movement of the carrier element (40); wherein the guide arrangement (60) is guided in the housing (11) in a straight line guide structure (14) and the carrier element (40) is guided in a guide track (21) extending essentially parallel to the guide structure (14) and a deceleration device (30) including a piston rod (34) is arranged in alignment with the guide track (21) with the piston rod (34) being connected to the carrier element (40).
