Seat cushion adjustment module

The invention relates to a seat cushion adjusting module, and in particular to a seat cushion adjusting module for a bicycle.

In general, the seat cushion of the bicycle can be adjusted by shifting or rotating the adjusting module relative to the seat tube to adjust the position of the seat cushion relative to the seat tube to match the different body shape of the rider, thereby increasing the comfort when riding the bicycle.

If you want to adjust the position of the seat cushion relative to the seat tube, just loosen the lock of the adjustment module so that the seat bow of the seat cushion can be translated or rotated relative to the seat tube, after the seat cushion is adjusted to the desired position. Then lock the lock firmware.

However, the proportion of the rider's body is variable. Even if the bicycle is of several sizes, the rider of the same height will have different geometrical things. It depends on the seat bow of the seat cushion relative to the seat tube. The translation adjustment range is limited by the shape of the seat bow. Although the horizontal adjustment section of the growth seat bow can be used to increase the translation adjustment range, this will increase the weight of the seat cushion and the ride will be too far forward or The rear side causes insufficient rigidity to sway like a seesaw, causing discomfort.

The invention provides a seat cushion adjusting module for connecting a seat cushion and a seat tube of a bicycle, and adjusting the position of the seat cushion relative to the seat tube.

The invention provides a seat cushion adjusting module suitable for connecting a seat cushion of a bicycle and a seat tube. The seat cushion includes at least one bow. The seat cushion adjustment module includes a base, a clamping unit and a locking unit. The base is adapted to be assembled to one end of the seat tube. The clamping unit includes a first clamping member and a second clamping member. The first clamping member has at least one first clamping portion and a shaft portion, wherein the shaft portion is coupled to the base in the first position or the second position to correspond to the first rotation axis or the second rotation axis relative to the base Rotate. The second clamping member has at least one second clamping portion, and the second clamping portion and the first clamping portion are adapted to jointly clamp the seat bow. The locking unit includes a first locking component and a second locking component. The second locking member cooperates with the first locking member to lock the first clamping member and the second clamping member to the base such that the first clamping portion and the second clamping portion jointly clamp the seat bow.

Based on the above, the present invention utilizes the shaft portion of the first clamping member to be coupled to the base in the first position or the second position, thereby increasing the translational adjustment range of the seat cushion relative to the seat tube.
