1. A centrifugal pendulum device for a damper assembly, comprising:
a weight carrier disc including at least one opening and guide tracks arranged on a radially outer region thereof and including damper spring openings in a radially inner region thereof;
a centrifugal weight disposed displaceably on the weight carrier disc, the centrifugal weight including two side elements that each include weight guide tracks, and spacing bolts arranged between the two side elements, at least one of the spacing bolts extending through the at least one opening of the weight carrier disc, the centrifugal weight being guided displaceably on the weight carrier disc by roller elements that run on the guide tracks and the weight guide tracks; and
the weight carrier disc comprises a first plate that includes the radially inner region connected to at least one second plate that includes the radially outer region, and the at least one second plate has a thickness that is at least 30% greater than a thickness of the first plate.
