In the closed state where the valve member 17 closes the passage PW, substantially incompressible fluid does not flow between the first hydraulic chamber C1 and the second hydraulic chamber C2. Thus, in the closed state, the first member 14 and the second member 16 are fixedly positioned relative to each other along the longitudinal direction D1.

In an open state where the valve member 17 opens the passage PW, substantially incompressible fluid can flow between the first hydraulic chamber C1 and the second hydraulic chamber C2 through the passage PW. For example, when the rider's weight is applied to the second member 16 in the open state, substantially incompressible fluid flows from the first hydraulic chamber C1 to the second hydraulic chamber C2 through the passage PW. Thus, the floating piston 34 is pressed against the first member 14 towards the deflection chamber C4, increasing the volume of the second hydraulic chamber C2, while the compressible fluid is compressed in the deflection chamber C4. This causes the second member 16 to move downward relative to the first member 14, resisting the deflection force of the deflection cavity C4 while the rider's weight is applied to the second member 16, allowing the rider to take advantage of the riding position in the open state. The weight of the person lowers the seat cushion.

The compressible fluid compressed in the deflection cavity C4 deflects the second member 16 to move upward relative to the first member 14 in the longitudinal direction D1 and to move the floating piston 34 downward in the longitudinal direction D1. When the rider's weight is released from the second member 16 in the open state, substantially incompressible fluid flows from the second hydraulic chamber C2 to the first hydraulic chamber through the passage PW due to the deflection force of the deflection chamber C4 C2. This moves the second member 16 upwardly relative to the first member 14 while the rider's weight is released from the second member 16, allowing the rider to raise the saddle in the open state releasing the rider's weight.

Thus, in the adjustable state, the first member 14 and the second member 16 can move relative to each other along the longitudinal direction D1. For example, when the rider's weight is applied to the second member 16 through the seat cushion secured to the seat cushion mounting structure MS, the second member 16 moves relative to the first member 14 along the second movement direction D32. When the rider's weight is released from the second member 16, the second member 16 moves relative to the first member 14 along the first moving direction D31 by the biasing force of the compressible fluid in the biasing cavity C4.

The controller 52 selects a detector adjacent to the reference detector within the second moving direction D32 as a second additional reference detector from the plurality of detectors H (step S6 ). If there is no detector adjacent to the reference detector in the first moving direction D31 , the controller 52 does not select any detector as the first additional reference detector. If there is no detector adjacent to the reference detector in the second moving direction D32, the controller 52 is configured not to select any detector as the second additional reference detector.

In the present invention, as used in this specification, the term "comprising" and its variations are open-ended terms specifying the presence of stated features, elements, components, groups, integers and/or steps, but not excluding the presence of other unspecified State features, elements, components, integers and/or steps. This concept also applies to words with similar meanings, such as the terms "have", "comprise" and their variations.

When the terms "member", "section", "part", "component", "element" and "structure" are used in the singular, they can have both the singular and the plural meanings.

Prefaces such as "first" and "second" in this specification are only identifiers and do not have any other meaning, such as a specific order and so on. Also, for example, the term "first element" does not in itself imply the presence of a "second element," and the term "second element" does not in itself imply the presence of a "first element."

As used in this specification, the term "pair" may cover configurations of paired elements having different shapes or structures from each other, as well as configurations of paired elements having the same shape or structure as each other.

In this specification, the leading "a" (or "an"), "one or more" and "at least one of" are used interchangeably.

The word "at least one" used in the present invention means an intended selection of "one or more". For an example, if the number of choices is two, the word "at least one of" used in the present invention means "only one single choice" or "both of two choices". For other examples, if the number of choices is equal to or more than three, the term "at least one of" used in the present invention means "only one choice" or "any combination of equal to or more than two choices". For example, the phrase "at least one of A and B" encompasses (1) only A, (2) only B, and (3) both A and B. The phrase "at least one of A, B, and C" covers (1) only A, (2) only B, (3) only C, (4) both A and B, (5) both B and C, (6) both A and C, and (7) all A, B and C. In other words, in the present invention, the phrase "at least one of A and B" does not mean "at least one of A and at least one of B".

Finally, terms of degree such as "substantially", "about" and "approximately" as used in this specification indicate a reasonable amount of deviation of the modified item such that the result is not significantly changed. All numerical values described in this application can be interpreted as including terms such as "substantially", "about" and "approximately".

Obviously many modifications and variations of the invention are possible in view of the foregoing. It is therefore understood that within the scope of the claims hereinafter, the invention may be practiced by examples other than those specifically described in this specification.
