A catch device of a lengthwise adjustment mechanism of a motor vehicle seat comprises a first pair of rails and a second pair of rails, each having a bottom rail and a seat rail. A first detent ledge is associated with the bottom rail and comprises first detent openings and first detent webs. A first stopper unit is disposed in proximity to the first detent ledge and cooperates therewith, comprises two stopper teeth for engaging the first detent openings independently of one another and for disengaging therefrom together and is associated with the seat rail of the first pair of rails. A second detent ledge is associated with the bottom rail of the second pair of rails and comprises second detent openings and second detent webs. A second stopper unit is disposed in proximity to the second detent ledge and cooperates therewith, comprises a stopper means for engaging and disengaging the second detent openings and is associated with the seat rail of the second pair of rails. An actuation unit has a hand lever and comprises actuator means through which the hand lever is connected to the two stopper units for common actuation of the stopper units. The second stopper unit has only one stopper means, which is a coherent part and is either in or out of engagement with at least one second detent opening.

The safety lock catch device of claim 1, wherein the spacing between two neighbouring second detent openings has the value z and that the clear distance between two neighbouring stopper teeth of the first stopper unit also has the value z. 3. The safety lock catch device of claim 1, wherein the length of a first detent opening is double the length of a first detent web. 4. The safety lock catch device of claim 1, wherein the width of a stopper tooth of the first stopper unit equals the length of a first detent web. 5. The safety lock catch device of claim 1, wherein the stopper teeth of the first stopper unit are all built identically. 6. The safety lock catch device of claim 1, wherein the first stopper unit is located on the side of the motor vehicle seat to which higher belt forces are applied as compared to the other seat side. 7. The safety lock catch device of claim 1, wherein the motor vehicle seat is a driver's seat or a passenger front seat and that the first stopper unit is located on the inboard side of the seat. 8. The safety lock catch device of claim 1, wherein the first stopper unit comprises at least three stopper teeth. 9. The safety lock catch device of claim 1, wherein the first stopper unit comprises three stopper teeth. 10. The safety lock catch device of claim 1, wherein the stopper part of the second stopper unit is configured to be a stopper comb which has at least two stopper projections. 11. The safety lock catch device of claim 1, wherein the stopper part of the second stopper unit is an integral part. 12. The safety lock catch device of claim 1, wherein the stopper part of the second stopper unit is a rigid part. 13. The safety lock catch device of claim 1, wherein the stopper part comprises at least two stopper projections, and wherein all of the stopper projections are either in or out of engagement with the at least one second detent opening. 14. The safety lock catch device of claim 1, wherein the stopper part has a different configuration than a stopper tooth of the at least two stopper teeth and from the at least two stopper teeth. 15. The safety lock catch device of claim 1, wherein at least one of the at least two stopper teeth is engaged with one of the first detent openings in any lengthwise adjustment position of the motor vehicle seat. 16. A safety lock catch device of a lengthwise adjustment mechanism of a motor vehicle seat, the lengthwise adjustment mechanism comprising a first pair of rails and a second pair of rails, each having a bottom rail and a seat rail; and the catch device comprising: a first detent ledge that is associated with the bottom rail of the first pair of rails and comprises first detent openings and first detent webs, a first stopper unit that is disposed in proximity to the first detent ledge and cooperates therewith, that comprises at least two stopper teeth for engaging the first detent openings independently of one another and for disengaging therefrom together and that is associated with the seat rail of the first pair of rails, a second detent ledge that is associated with the bottom rail of the second pair of rails and that comprises second detent openings and second detent webs, a second stopper unit that is disposed in proximity to the second detent ledge and cooperates therewith, that comprises only one stopper part that engages and disengages the second detent openings and that is associated with the seat rail of the second pair of rails, the stopper part is a coherent part and is either in or out of engagement with at least one second detent opening, an actuation unit that has a hand lever and comprises actuator means through which the hand lever is connected to the two stopper units for common actuation of the stopper units, wherein the first detent ledge has a period size P1, the second detent ledge has a period size P2, and the period size P1 of the first detent ledge is n-times the period of the period size P2 of the second detent ledge, whereby n is an integer. 17.
