Seat support structure

A seat support structure which supports a seat by engaging an engaging groove portion formed on an outer peripheral portion of a mount rubber in an opening portion of a seat support portion of a vehicle and by inserting a portion of the seat to be supported into a through hole formed in a mount rubber, wherein

• at a seat mounting position where an insertion portion of the mount rubber arranged closer to a distal end side than the engaging groove portion is inserted into the opening portion of the seat support portion and the portion of the seat to be supported is inserted into the through hole formed in the mount rubber, the mount rubber is moved in a radial direction in an inside of the opening portion, and a portion of a groove wall of the engaging groove portion is brought into pressure contact with the opening portion,
• wherein a diameter of the engaging groove portion is set smaller than a diameter of the opening portion of the seat support portion,
• wherein the portion of the seat to be supported includes portions in pairs are arranged on the seat in a spaced-apart manner,
• the opening portion including opening portions in the same number of pairs as the portions to be supported arranged on the seat support portion in a spaced-apart manner, and
• the mount rubber includes mount rubbers in pairs in the same number of pairs as the opening portions,
• wherein a distance (WP, WPa) between the portions to be supported in pairs is made different from a distance (WH, WHa) between the opening portions in pairs, and the mount rubbers are formed with a distance equal to the distance between the respective through holes formed in the mount rubbers in a state that the mount rubbers are moved to the distance (WP, WPa) between the portions to be supported and portions of the engaging groove portions are brought into pressure contact with the opening portions respectively.

A seat support structure for supporting a seat with a portion to be supported, the seat support structure comprising:

• a seat support portion of a vehicle, the seat support portion having a circular opening portion;
• a mount rubber having an circular engaging groove portion formed on an outer peripheral portion thereof, an insertion portion arranged closer to a distal end side than the engaging groove portion, and a through hole penetrating from top to bottom of the mount rubber;
• wherein at a mounting position of the seat,
• the insertion portion of the mount rubber is inserted into the opening portion of the seat support portion,
• the portion of the seat to be supported is inserted into the through hole formed in the mount rubber, and
• the mount rubber is moved in a radial direction in an inside of the opening portion, so that an axial center line of the mount rubber is offset from an axial center line of the opening portion, and a portion of a circular groove wall of the engaging groove portion is brought into pressure contact with the opening portion,
• wherein a diameter of the engaging groove portion is set smaller than a diameter of the opening portion of the seat support portion.
