A fixing member is arranged on one side of the chassis. The slide rail assembly comprises a guide rail having a first rail section, a second rail section and a third rail section. The first rail section is configured to support a portion of the chassis. A path is defined between the second rail section and the third rail section for allowing the fixing member on the chassis to pass through. ## Claims ### Claim 1 A slide rail assembly for a rack system, configured to mount a chassis to a rack, a fixing member being arranged on one side of the chassis, the slide rail assembly comprising: a guide rail having a first rail section, a second rail section and a third rail section, wherein the first rail section is bent relative to the second rail section for supporting a portion of the chassis, the third rail section is arranged above the second rail section, a path is defined between the second rail section and the third rail section for allowing the fixing member on the chassis to pass through; wherein when the chassis is mounted to the guide rail, the fixing member on the chassis passes through the path of the guide rail, and the fixing member on the chassis abuts against one of the second rail section and the third rail section of the guide rail. ### Claim 2 (depends on 1) The slide rail assembly of claim 1, further comprising a supporting frame, wherein the guide rail is movably connected to the supporting frame. ### Claim 3 (depends on 2) The slide rail assembly of claim 2, wherein the guide rail has abounded longitudinal hole, and is connected to the supporting frame through a connecting member passing through the longitudinal hole, such that the guide rail is movable relative to the supporting frame within a limited space. ### Claim 4 (depends on 1) The slide rail assembly of claim 1, wherein the fixing member on the chassis has a first fixing part and a second fixing part connected to the first fixing part, the first fixing part is connected to the chassis, an outer diameter of the second fixing part is greater than an outer diameter of the first fixing part; wherein when the chassis is mounted to the guide rail, the fixing member on the chassis passes through the path of the guide rail, and the first fixing part of the fixing member on the chassis abuts against one of an upper edge of the second rail section and a lower edge of the third rail section, one side of the second rail section and one side of the third rail section of the guide rail are configured to support another portion of the chassis. ### Claim 5 (depends on 1) The slide rail assembly of claim 1, wherein the second rail section of the guide rail is located at a front end of the guide rail, the guide rail further has a rear blocking part located at a rear end of the guide rail. ### Claim 6 (depends on 5) The slide rail assembly of claim 5, wherein the third rail section of the guide rail is extended along a longitudinal direction of the first rail section of the guide rail and connected to the rear blocking part. ### Claim 7 (depends on 5) The slide rail assembly of claim 5, wherein the rear blocking part of the guide rail is extended with a rear supporting part, an upper edge of the rear supporting part is configured to abut against the fixing member on the chassis. ### Claim 8 A slide rail assembly for a rack system, configured to mount a chassis to a rack, a fixing member being arranged on one side of the chassis, the slide rail assembly comprising: a guide rail having a first rail section, a second rail section and a third rail section, wherein the first rail section is bent relative to the second rail section for supporting a portion of the chassis, the third rail section is arranged above the second rail section, a path is defined between the second rail section and the third rail section for allowing the fixing member on the chassis to pass through; wherein the fixing member on the chassis has a first fixing part and a second fixing part connected to the first fixing part, the first fixing part is connected to the chassis, an outer diameter of the second fixing part is greater than an outer diameter of the first fixing part, wherein when the chassis is mounted to the guide rail, the first fixing part of the fixing member on the chassis abuts against a lower edge of the third rail section of the guide rail, and one side of the second rail section and one side of the third rail section of the guide rail are configured to support another portion of the chassis. ### Claim 9 (depends on 8) The slide rail assembly of claim 8, wherein the second rail section of the guide rail is located at a front end of the guide rail, the guide rail further has a rear blocking part located at a rear end of the guide rail, the third rail section of the guide rail is extended along a longitudinal direction of the first rail section of the guide rail and connected to the rear blocking part. ### Claim 10 A slide rail assembly for a rack system, configured to mount a chassis to a rack, a fixing member being arranged on one side of the chassis, the slide rail assembly comprising: a guide rail having a first rail section, a second rail section and a third rail section, wherein the first rail section is bent relative to the second rail section for supporting a portion of the chassis, the third rail section is arranged above the second rail section; wherein the fixing member on the chassis has a first fixing part and a second fixing part connected to the first fixing part, the first fixing part is connected to the chassis, an outer diameter of the second fixing part is greater than an outer diameter of the first fixing part, wherein when the chassis is mounted to the guide rail, the first fixing part of the fixing member on the chassis abuts against an upper edge of the second rail section of the guide rail, and one side of the second rail section and one side of the third rail section of the guide rail are configured to support another portion of the chassis. ### Claim 11 (depends on 10) The slide rail assembly of claim 10, wherein the second rail section of the guide rail is located at a front end of the guide rail, the guide rail further has a rear blocking part located at a rear end of the guide rail, the rear blocking part of the guide rail is extended with a rear supporting part, an upper edge of the rear supporting part is configured to abut against the fixing member on the chassis.
