1. A suspension thrust bearing device comprising:
a lower support cap having a rigid main body, the rigid main body containing a reinforcing insert,
an upper bearing cap,
at least one bearing arranged between the upper bearing cap and the lower support cap, the at least one bearing having a lower race, the rigid main body being in direct contact with the lower race of the at least one bearing, and
a flexible vibration damping seat of the lower support cap delimiting a bearing surface for the upper end of a suspension spring, wherein the flexible vibration damping seat
is secured to the rigid main body, the flexible vibration damping seat having an axially extending annular skirt which when viewed in cross-section has at least one retaining hook extending radially outwardly therefrom and which is axially offset with respect to the bearing surface on a side opposite to the at least one bearing,
wherein the reinforcing insert has an axially extending portion and a radially extending portion, when viewed in cross-section the reinforcing insert is fully enclosed within the rigid main body, and
wherein the at least one retaining hook of the flexible vibration damping seat does not radially overlap the axially extending portion of the reinforcing insert.
